Application: kontact (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.8.0
Operating System: Linux 3.2.6-3.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed:

In Kontact , in the Kmail window, in a folder view, when a mail with an attachement is shown. Right click on a attachement, and choose "remove the attachment". That crashes Kontact.

The mail is stored in a remove imap server. As a matter of fact, the attachement that I try to remove is not removed.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
