            Bug ID: 347743
           Summary: kmail crashes while moving / deleting messages
           Product: kmail2
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: richard at ytivarg.com

Application: kmail (4.14.6)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Moving messages from one folder to another.  

- Unusual behavior I noticed:
It was necessary to move messages one at a time.  If I select multiple
messages, it would give a tiny dialog with only "OK" in it.  After emptying one
folder, I said "delete" and then kmail appeared to go into some kind of endless
loop, ignoring input.  Window controls work: I quit the app.  This caused a
zombie process that I had to kill -9.

- Custom settings of the application:
flattest possible message sorting -- simple date-sent order with no threading.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
