KMail has crashed twice when I deleted mails. I used shift-delete to delete them, as opposed to moving them to the wastebin. On the second occasion (I can't remember what the exact circumstances were the first time), I deleted the last 3 items from one folder as a group. When I restarted kmail after the crash, two of the mails were gone, but the third was still in the folder.
