Comment 1 for bug 287614

Also several gtk applications (e.g. rhythmbox, pidgin) quit with this message:

~$ pidgin
/home/twice/.gtkrc-2.0:7: Impossibile trovare il file da includere: ".gtkrc-2.0-gnome-color-chooser"

ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib/gstreamer-0.10/libgstlibvisual.so

Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.

~$ pidgin --debug
