Bugzilla Bug 165586

Every time I run a KDE app I get hundreds of warnings on the console, like:

kbuildsycoca: WARNING: '/usr/share/applications/gqview.desktop' specifies
undefined mimetype/servicetype 'image/x-xbitmap'

However, the relevant mime entries seem to be there, e.g.:

$ ls -l /usr/share/mime/image/x-xbitmap.xml
-rw-r--r-- 1 root root 530 Jan 28 09:42 /usr/share/mime/image/x-xbitmap.xml

Reproducible: Always

Steps to Reproduce:

Hey yea!  What up wit this? 

(Know one things, it been around for awhile but I rarely run KDE, so figured it
was something known a year ago. :-/ )

$ qfile /usr/kde/3.5/bin/kbuildsycoca
kde-base/kdelibs (/usr/kde/3.5/bin/kbuildsycoca)

$ qfile /usr/share/applications/<insert any other file name here> 


kbuildsycoca is owned and compiled by kdelibs.  It looks as if kbuildsycoca is
parsing a universal folder /usr/share/applications/ and is having errors with
parsing /usr/share/applications/* files not owned by kde (ie. gnome,
openoffice, ...)

Can it be fixed?  I'm not sure because kbuildsycoca has been compiled and
installed recently here.

Hopefully somebody (such as a KDE geek ;-) will know a better answer to this
trivial problem.

Same thing here - but also this:

kbuildsycoca running...
Reusing existing ksycoca
kio (KSycoca): ERROR: No database available!
kbuildsycoca: WARNING: 'qeditor_part.desktop' specifies undefined
mimetype/servi
cetype 'text/english'


and than hundreds more of the last one.

This was a fresh install - deleted all .kde* in $HOME and removed /usr/kde/3.5
completly.
The first time it works - kcontrol run fine,kaffeine too.
But when i start kaffeine the second time the error is there again - although
it was a fresh install.

Cant get it working again, kcontrol also show a empty control panel, only a
network folder is there and a message like this:

kcontrol: WARNING: No K menu group with X-KDE-BaseGroup=settings found !
Defaulting to Settings/

I'm having the same issue with 2 of three PCs. Anyone have any thoughts?

The problem is apparently old, superceded crap in /usr/kde/3.5 as per this post
in the gentoo forums: http://forums.gentoo.org/viewtopic-p-3732879.html#3732879

Several points: The +10 days mentioned in the post is specific to that person's
configuration. i.e. Your situation is certain to vary. 

I tried +35 days on one system and that turned out to be not such a good idea.
It looks like I'll need to rebuild kde on that box from scratch. The mime issue
was eliminated but I lost some compiled programs I needed. I needed to do a
larger number of days.

When all else fails, I suggest that you completely clear out /usr/kde/3.5 and
rebuild kde from scratch. This is a last resort suggestion.

You did not read my post, did you?
Again : I have cleared out all!

It works one time fine - but after reboot/shutdown/suspend its broken again.

So this is still an issue i would say - because i dont know why this happens, i
dont want to clear out every reboot all kde*.

kind regards

Found a solution, which may work:

XDG_DATA_DIRS and XDG_CONFIG_DIRS is only set to directories used by xfce.
Extending these ones by the ones kde uses, it starts working again.

kind regards

(In reply to comment #7)

In my environment these are not defined at all. If I set to e.g.

setenv XDG_DATA_DIRS $KDEDIR/share/:/usr/share/
setenv XDG_CONFIG_DIRS $KDEDIR/etc/xdg/:/etc/xdg/

nothing changes.

In my environment ( xfce4 ) kde works again and its working everytime, and my
menu has more kde program entries, without them they are gone.
So here it changes a lot. 

I've also defined the other 2 XDG entries XDG_DATA_HOME= and XDG_CONFIG_HOME.

kind regards

I think here are two different issues mixed. First, the kbuildsycoca warnings
do not matter. Ignore them. Ubuntu has even silenced them, but I'm not sure, if
this makes a lot of sense. Second, the XDG variables matter only for users of
other desktops than KDE. XDG_DATA_DIRS is already set, XDG_CONFIG_DIRS will be
with the next revsion bump I'm preparing.

Right.  Sort of like beating my console to death with a baseball bat.  If these
are truly meaningless errors for other users, they should be only outputed with
the optional "-v --verbose" switch.

<shrugs>... my opinion.

Well, if they are really harmless, it's best to silence them. But why do they
exist at all?? I guess KDE folks never run anything from the command prompt
;-). The tons of these stupid messages may shadow really important warnings an
app is issuing (especially since the kbuildsycoca warnings appear
asynchronously).

Well, the output can be helpful, when there're really issues and for testing
purposes. I don't think it's a good idea to remoove the possibility to do so.
And no, while KDE apps can be quite verbose, I do not get a lot of these,
because I do not have a lot of applicatons installed, which install mimelnk
stuff, which isn't available in KDE's mimelnk db. 

Push the output to /dev/null if you don't like it and if you're too lazy to do
this each time on the commandline, create an alias.

Please re-read the bug description. I repeat: the warnings are WRONG in this
case, as the mime db entries ARE there.

KDE 3 uses it's own mime db, not the shared one.

(In reply to comment #15)
> KDE 3 uses it's own mime db, not the shared one.

So why the hell it tinkers with the _shared_ .desktop entries?! Any advise on
how to stop it doing stupid things like this while keeping correct warnings
displayed?

mime db entries != desktop entries

*sigh*, long explanation: The shared mime db is in /usr/share/mime KDE gathers
its information from the .../share/mimelnk/ subdirectories with the directories
in $KDEDIRS plus your KDE home dir as base. So, taking the inital mimetype as
example, we have 

/usr/share/mime/image/x-xbitmap.xml (shared mime db)

and the corresponding

/usr/kde/3.5/share/mimelnk/image/x-bmp.desktop  (dont be tricked by the
.desktop ending, it's not a xdg compliant desktop entry)

Now you could think renaming x-bmp.desktop to x-xbitmap.desktop would do, but
wrong: You'd also need to go through the _whole_ KDE sources and replacing all
occurences of MimeTyp=image/x-bmp in all application desktop-entries (that is
with Type=application in them) with image/x-xbitmap. The latter job is
scriptable of course, but you still have lookup and compare the mime db's
manually. Hell of a job, but if you like it, I'm sure the kde.org devs
appreciate your patches.

(In reply to comment #17)
> mime db entries != desktop entries

My point is KDE parses the whole /usr/share/applications/ dir (which is NOT
KDE-specific), and thus pretends to be a good netizen. On the other hand, when
time comes to understand it, it forgets about anything but itself. This is just
plain inconsistent (it's not a Gentoo's failure, of course, but I'd like to see
a remedy e.g. like what Ubuntu folks did).

No, /usr/share/applications/ is not KDE specific, but that doesn't mean there
aren't desktop entries to process in it.

Reminds me of Microsoft.  Microsoft binaries report no debugging info.

But with KDE, seems they want to obtain the same objective, but with
overloading us with debugging output.  Maybe they just want to irritate Gnome
users?

:-/

This is really a KDE bug.  KDE devs should really group this debug output into
a higher debug level instead of displaying this junk with other more useful
debug info.  Or is this only possible when using C? <grin>
