Kicker crashing [Solved]

[Raqua]

I had this problem when I emerged the latest kicker version. I do not remember the exact number and can not check it right now as I am in work, but I suppose it was 3.5.7-r2.
Kicker was crashing on me with these symptoms:


Using host libthread_db library "/lib/libthread_db.so.1".

It crashed 1-2 times in a hour, so it is very anoying. First time I get this crash, it seems like KDE is able to recover and restart kicker and panels, but when I got this error for the second time, I lost panels. I do not see them and can not use them, but KDE seems otherwise working. I can swith between apps using ALT+TAB etc..

If someone has similar problem, reverting to version 3.5.7 solves it.
