Description kondor6c 2017-11-15 18:41:08 UTC

Application: kdeinit5 (5.0.97)

Qt Version: 5.7.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.11-200.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
- What I was doing when the application crashed:
It appears to be when I open a tab to stackoverflow, I attempted to duplicate this multiple times and it seem to crash multiple times. I sent a sig 6 to the process and it crashed, I'll see if I can generate another one

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (kdeinit5), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
