Can you please try to install the debug packages for kdebase, and get a better backtrace?
Comment 2 Andrew Fink 2008-04-25 16:37:14 UTC 
Yes absolutely.  Also I have new information, this crash only happens
when the add widget dialog is on the right monitor. New backtrace below.
Thanks!

Can you please try to install the debug packages for kdebase, and get a
better backtrace?
Comment 3 Sebastian Sauer 2008-06-03 20:07:16 UTC 
probably a dup of bug #162829
Comment 4 Thomas Georgiou 2008-07-05 17:53:30 UTC 
Can you reconfirm this with 4.1?
