GMail over IMAP:
When I tried to delete a mail, the process needed quite some time so I deleted other mails in between. When I then tried to select the "hanging" mail again, I accidently double-clicked. A separate message window appeared, I closed it -> KMail crashed with the following backtrace.

Application: KMail (kmail), Signal SIGABRT
