KDE Platform Version: 4.4.2 (KDE 4.4.2)

Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I just changed my Sieve script to filter Spam mails. The version beforehand moved mails to Trash (can't remember why), now I chose my Spam folder. To move all my Spam mail (~5000+) from Trash to Spam I created a Search looking for X-Spam-Flag == YES, chose the Search folder, selected all mail and dragged and dropped them into the Spam folder.

This took ages so I went away. I think first I tried to open my Inbox which failed because KMail was busy. Anyway, when I just came back to my place after an hour or so, KMail was crashed.

I just restarted KMail and it moved/copied ~5800 mails to the Spam folder while I still have ~500 (spam) mails in the Trash folder.

 -- Backtrace:
