Bug 357519

Application: kdeinit5 (15.08.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.8-200.fc22.x86_64+debug x86_64
Distribution: "Fedora release 22 (Twenty Two)"

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

I had just run some commands to provide info for a bug related to conflicts in installing debug-info for Konsole. I attempted to save the Konsole output when this crash occurred. My browser, xosview and all Konsole instances have crashed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/usr/lib64/libthread_db.so.1".
