Ok, this particular core was generated when I was tried to enable desktop effects from system settings app. But same thing happens on session start as well.

Comment 3 Beat Wolf 2011-04-12 10:41:16 UTC 
there are two different crashes here.
The first one is a plasma desktop crash, and the second one is a kwin crash.

Could you resubmit the second one as a kwin bug? thank you
Comment 4 kovrov 2011-04-12 10:43:50 UTC 
I wonder if it is related to memcpy issue on 64-bit atch. (reported here https://bugzilla.redhat.com/show_bug.cgi?id=638477).

Well, for me it is wery relared issues. Sorry for messed report. let me clarify.

1. On startup, kwin crashes. Desktop effects being disabled. This is second backtrace, as in comment #2. This happens allways.

2. Attempt to enable desktop effects from systemsettings app allways lead to kwin crash. This is backtrace initially reported. Desktop effects become enabled on 2-5 try.
