Description Richard Johnson 2016-07-09 22:06:44 UTC 
Application: kmail (5.1.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-28-generic x86_64
Distribution: Ubuntu 16.04 LTS

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

1. Imported some old mail  (some was kmail, some was old dir tree, and some was mbox ... all imported)
2. click on non-empty imported folder
3. drag to "inbox"
4. kmail crash, segmentation violation
5. restart kmail
6. directory that was indicated shows in correct place now

repeat 1 .. 4
insert "report crash"
5 and 6 also consistent still

The crash can be reproduced every time.

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