Bug 366847

Application: kdevelop (4.90.92)

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.6.6-300.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
- What I was doing when the application crashed:
Running KDevelop on python3 program from bazaar branch.
Fedora 24 with latest upgrades as of 16 August 2016
Crash occurs after opening a file when either closing using window 'X' or selecting
'Session->Quit'
Crash does not appear when I start KDevelop and immediately close without loading/viewing/editing any file in bazaar branch.

- Unusual behavior I noticed:
None during use

- Custom settings of the application:
None that I am aware of

The crash can be reproduced every time.

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