Description Laurent RINEAU 2012-02-20 15:29:42 UTC 
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".

New crash information added by DrKonqi

kontact (5.11.3) using Qt 5.12.4

- What I was doing when the application crashed:
I was deleting attachments in a kmail session inside kontact


- Unusual behavior I noticed:
I always manage to delete the first attachment, but the whole application (kontact) crashed when I try to delete a second attachment.
