Bug 195870

Version:           1.11.4 (using 4.2.4 (KDE 4.2.4), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.28-11-generic

I thought I reported this bug already but can't find it. This bug is quite reproducible and happens often but not always (but annoys the hell out of me).

A way to trigger it is my usual mail reading behaviour
1. Go to Inbox which has a bunch of unread mails.
2. Select the first so I can skim it in the preview pane.
3. Notice I'm not interested, hit delete, mark next mail.
4. Not interested as well, hit delete again (while the old operation is still in progress).
5. Crash.
6. Restart KMail. Notice the two mails were not deleted.

The server is a Dabian sarge running Dovecot 0.99.14-1sarge0 (from backports I think).

Application: KMail (kmail), signal SIGSEGV
