Bug 194822

If you're able to reproduce this issue, please read the following page and paste a backtrace for this crash: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Backtrace pasted below as requested.

Not sure if it helps, but I noticed while reproducing this that it does not seem to crash if only icons are displayed on the taskbar.  Displaying "text under icons" and using the steps above causes the crash. 

Backtrace:



Application: Kontact (kontact), signal SIGSEGV

Looks like a kdelibs bug.
