Unfortunately the backtrace is useless. If you are able to reproduce please install package kdebase-workspace-dbg and attach a new backtrace.

Comment 2 Thomas Lübking 2010-06-29 17:57:23 UTC

it's likely in oxygens sizegrip eventfilter, though
(backtrace structure, hugo has presumingly meanwhile fixed that)

try setting it to "always hide" in the "fine tuning" tab.
if it stops crashing, this is a dupe of the mentioned (if not the grip could be created but just hidden anyway)
