It appears to be ibus-qt trying to access an out of range index on a list.

This still happens on 12.04.

Removing ibus-qt4 and libibus-qt1 (probably only needed to remove libibus-qt1) seems to fix this, and it didn't force me to remove kubuntu-desktop as I had feared. Of course, for those who need ibus, that's hardly a viable solution.

This bug was fixed in the package ibus-qt - 1.3.1-2.1ubuntu3

ibus-qt (1.3.1-2.1ubuntu3) saucy; urgency=low

  * Add upstream_DISPLAY_crash_fix.diff preventing a crash when -display
    was passed but no DISPLAY environment variable is actually defined
