[Bug 65863] kminipager crash

[Laurent Bonnaud]

Public bug reported:

Binary package hint: kicker

My laptop has a 1680x1050 screen.  I sometimes change the resolution to
1024x768 to use a video-projector. The system crashed while the
resolution was 1024x768 and on the next reboot the resolution was still
1024x768.  I changed the resolution back to 1680x1050 but the minipager
applet was ridiculously small.  To fix this, I tried to remove it from
the kicker panel and re-add it.  When I tried to add it again, it
crashed with this backtrace:

Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
