Description aschmidt 2016-06-17 23:57:42 UTC

Application: kdevelop (4.90.92)

Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.5-300.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
I closed kdevelop with about 8 tabs open, and then immediately went to log out.

I've done this times without number, but this time, it threw an error. It's not easy to reproduce.

The crash does not seem to be reproducible.

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