Comment 1 Jekyll Wu 2011-12-11 11:50:05 UTC 
This report is against a quite old version, and some debugging symbols are missing in the backtrace. 

If this crash still happens in recent version, please install those missing debugging symbols(should be 'kdebase-workspace-dbg' in debian) and post the backtrace here.
