Actually, repeatably, I just get this. I'm sure you guys know why all that extra stuff got generated.... :-)

Comment 2 Dario Andres 2009-02-03 13:04:07 UTC 
It looks like a bug in the file-dialog. If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? 
Thanks :)

Comment 4 Michael Jansen 2009-02-23 00:47:01 UTC 
SVN commit 930297 by mjansen:

Fix crash when using KFileWidget without calling setMode().

This was an behaviour incompatible change. Applications that worked perfectly
before now fail with an assertion, i have no idea what would happen in
release mode. I tried to bring back the behavior from  before change 861225.

If the fix get oked please backport.
