Bug 279832 – dev-python/libwnck-python-2.30.2 will not run correctly with x11-libs/libwnck-2.30.2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Jim Ramsay (lack) (RETIRED) 2009-07-31 22:53:58 UTC]

$ python -c "import wnck"

** (-c:15390): WARNING **: Trying to register gtype 'WnckWindowState' as flags when in fact it is of type 'GEnum'

** (-c:15390): WARNING **: Trying to register gtype 'WnckWindowActions' as flags when in fact it is of type 'GEnum'

** (-c:15390): WARNING **: Trying to register gtype 'WnckWindowMoveResizeMask' as flags when in fact it is of type 'GEnum'

The end result is that the various constants defined in these 3 enumerations are no longer available via that module, so any program (Such as rox-base/tasktray which uses them) will fail.

If I downrev to x11-libs/libwnck-2.26.1 everything works just fine.

I suggest adjusting the libwnck-python ebuild to depend on "<=x11-libs/libwnck-2.26.1"

I'll also try reporting this upstream, if I can figure out where/how.

Afaics, it is just a warning. Could you report this at http://bugzilla.gnome.org and paste the URL here ?

No, unfortunately it's a warning that also means "We did not register those values, so you can't use them in a program", so any python app that tries to use, say, wnck.WINDOW_STATE_URGENT will suddenly get an AttributeError!

Try this:
  python -c "import wnck; print wnck.WINDOW_STATE_URGENT"

With libwnck-2.26.1 I get:

<flags WNCK_WINDOW_STATE_URGENT of type WnckWindowState>

With libwnck-2.66.2 I get:

** (-c:20623): WARNING **: Trying to register gtype 'WnckWindowState' as flags when in fact it is of type 'GEnum'

** (-c:20623): WARNING **: Trying to register gtype 'WnckWindowActions' as flags when in fact it is of type 'GEnum'

** (-c:20623): WARNING **: Trying to register gtype 'WnckWindowMoveResizeMask' as flags when in fact it is of type 'GEnum'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'WINDOW_STATE_URGENT'

Fixed in libwnck-2.6.2-r2 and submitted a patch upstream.

[Comment 5 Jim Ramsay (lack) (RETIRED) 2010-07-21 04:52:04 UTC]

Oh no, it's back.  After upgrading to 2.30.2:

$ python -c "import wnck"

** (-c:21056): WARNING **: Trying to register gtype 'WnckWindowState' as enum when in fact it is of type 'GFlags'

** (-c:21056): WARNING **: Trying to register gtype 'WnckWindowActions' as enum when in fact it is of type 'GFlags'

** (-c:21056): WARNING **: Trying to register gtype 'WnckWindowMoveResizeMask' as enum when in fact it is of type 'GFlags'

I'll see if I can find some time to look into the root cause, but the patch submitted to upstream last time this happened looks like it's still there.  Something else must be going wrong.
