[pazuzuthewise]

Gimp doesn't start under KDE4, outputs the following error:
---------
(gimp:3233): GLib-WARNING **: /build/buildd/glib2.0-2.28.6/./glib/goption.c:2132: ignoring no-arg, optional-arg or filename flags (8) on option of type 0
Segmentation fault

Tried to use the older gimp package available in the ubuntu repository (2.6.11-1ubuntu6) with the same effect.

You can fix this by changing the widget style in 'GTK+ Appearance - System Settings' from oxygen-gtk to Raleigh, starting, then closing Gimp, then switching the widget style back to oxygen-gtk.
