Bugzilla Bug 106144

Since gnome 2.12 in in portage I'm unmasked it using package.keywords and
package.unmask.

app-crypt/seahorse-0.7.9 which I believe is needed for Evolution* to do inline
PGP fails with the following error (below)



Reproducible: Always
Steps to Reproduce:
1. Install Gnome 2.12 (i guess gedit 2.12.0 is the cause)
2. emerge seahorse-0.7.9 (which is ~arch)
3.

Actual Results:  
enabling key server support
enabling gedit plugin...
checking for supported versions of gedit...
checking for gedit-2.10 >= 2.9.0... checking for gedit-2.8 >= 2.8.0... checking
for gedit-2.6 >= 2.6.0... Package gedit-2.6 was not found in the pkg-config sear
ch path. Perhaps you should add the directory containing `gedit-2.6.pc' to the P
KG_CONFIG_PATH environment variable No package 'gedit-2.6' found
configure: error: Library requirements (gedit-2.6 >= 2.6.0) not met; consider ad
justing the PKG_CONFIG_PATH environment variable if your libraries are in a nons
tandard prefix so pkg-config can find them.

!!! Please attach the config.log to your bug report:
!!! /var/tmp/portage/seahorse-0.7.9/work/seahorse-0.7.9/config.log

!!! ERROR: app-crypt/seahorse-0.7.9 failed.
!!! Function econf, Line 485, Exitcode 0
!!! econf failed
!!! If you need support, post the topmost build error, NOT this status message.


Expected Results:  
seahorse to compile correctly,
hence allowing evolution to do inline PGP stuff (evolution complains that it
couldn't try to the seahorse socket (because seahorse DNE).

Even more info.

In capplets/background/gnome-wp-item.c at line 221 there is an:

if (pixbuf != NULL) { 
   ...
}

Right after that block there is a:

pw = gdk_pixbuf_get_width (pixbuf);
ph = gdk_pixbuf_get_height (pixbuf);

Those generates the warnings, since pixbuf obviously is NULL. Looks like they
handle that. But the "g_object_unref (pixbuf)" does not it makes the capplet
segfault.

Now, I wonder: why is pixbuf NULL at all? Should there be a

if (pixbuf == NULL) return;

statement somewhere before?

I have no experience of gtk/gnome programming, but it looks like there is a
missing check if the pixbuf is created sucessully or not somwhere.

I also suspect that this only happens to a certain types of files and not all.

> Even more info.

Oups... This was in the wrong bug... My comment is not related to this at all.
I'm sorry.

Seahorse seems to require gedit 2.10, while gnome 2.12 has gedit 2.12. 
Upstream
will need to update it to make it work with 2.12.

I've patched it and added to CVS.
