Bug 286185

Since the 'plasma-desktop' crashing... bug doesn't crash kdiff3 but might be the reason for other 'plasma-desktop' crashings like starting eclipse from konsole (happens sometimes), I add the crash info. Before KDE 4.7.3 the system was very stable, but now the crashing... seems to be 'standard' behaviour.

Sorry, the plasma crash is the duplicate, the kdiff3 issue is still unconfirmed.

I am not sure what you are reporting here:

1) Crash in taskmanager
2) "not found" message in kdiff3

Please decide and report the issues separately.

@1) Sorry, Revision 83f422db from Comment #20 of Bug 272495 is not yet in
http://download.opensuse.org/repositories/KDE:/Distro:/Factory/openSUSE_11.4/

Verified in groupmanager.cpp with
> mc kdebase4-workspace-4.7.3-694.1.src.rpm

which still reads:
    geometryTasks.remove(taskItem->task().data());
and not:
    geometryTasks.remove(taskItem->task());

@2) Sorry, the "not found" message in kdiff3 was present already in openSUSE 11.2.
