When searching a large IMAP folder (an error log from an mailing list I manage) kmail (run from within kontact) crashes when the queries return more than 150-200+ messages.

Here is a back trace:

System configuration startup check disabled.

Using host libthread_db library "/lib64/libthread_db.so.1".
