-- Information about the crash:
I had previous similar problems but where fixed after reinstall and system update.
I wanted to close Kopete because im in yahoo doesn't work right(it doesn't send what i type) and pressed Ctrl+Q. It has a 1-3 seconds lag and then the window dissappears. I launched pidgin, and plasma crashed. I suspect it is because Kopete losses the connection from Yahoo!, but of course i don't really know.
It happened before, but i didn't send any bug reports. 
Sorry for my bad english.

The crash can be reproduced some of the time.
