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 :)
Yes, the bug reproducable. Just after starting Kmail/Kontact when you are entering the inbox Kmail/Kontact crashes.

@Kacper: your crash is bug 179765 (already fixed in 4.2final). However this may be the same as the original bug report or not. Let's wait for the reporter reply. Thanks
I'm recompiling some things with debugging support... hopefully resulting in a better backtrace later today.
Is this already useful? I recompiled kdelibs and kmail with debug symbols but libkmailprivate.so.4 still doesn't show them... Program received signal SIGSEGV, Segmentation fault.

Please look at bug 179645. The backtraces are similar.
Seems to be fixed by cleaning up .kde4.2/share/kmail/*
@Silas: next time try moving that folder to another place instead of completely deteleting it (as it may contain useful information for you, and for us to triage the bug) Now I'm closing this as WORKSFORME. Please, reopen this bug report if you experience the same bug again. This may be related to bug 179645 but we can't be properly sure.
