Bug 183147

Version:           1.11.0 (using KDE 4.2.0)
Installed from:    Ubuntu Packages

When firing up kmail, the first thing I do is cleaning up my inbox. I just display mail with status "new", and do the following:

(1) Select a bunch of mail I can see in the contact list, and hit delete.
(2) While deleting is in progress I select some other mail and hit delete again.
(3) Goto (1)

This procedure terminates after one at most three iterations. The computed function is a crash report with this backtrace:

Application: KMail (kmail), signal SIGSEGV

I can observe this behavior since using kmail for kde 4. Always using packages from ubuntu's ppa repository.
