Okay, I get this reproduced. I didn´t close a previous DrKonqi crash 
windows that I didn´t notice then anymore.

So here goes:

But it needs debug symbols for

martin@merkaba:~> dpkg -S /usr/lib/kde4/libkdeinit/libkdeinit4_kwin.so
kde-window-manager: /usr/lib/kde4/libkdeinit/libkdeinit4_kwin.so

At least it seems to crash at blur effect creation.

However I didn´t find a dbg package for it. Is the dbg package named
