Bug ID: 362965
Summary: DrKonqi crashes opening DrKonqi on every crash...
Product: drkonqi
Version: 5.6.3
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org

If I have a crash (such as bug #362964) that causes DrKonqi to display, and
then click Report Bug, no matter what action I take DrKonqi crashes during exit
with the following backtrace:
Application: drkonqi (drkonqi), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

I cannot report this using DrKonqi due to bug #354564. I guess it's all for
the best, because then it would be a never ending loop.
Clicking Close without reporting the bug does not crash, so there is a way out.
Reproducible: Always
Steps to Reproduce:
1. Have something crash (not too hard, you can write a simple kf5 app that
calls abort() or such I suppose if you provide a report URL).
2. Click Report Bug in the DrKonqi window.
3. Do anything you want - go ahead and report it, or just click Cancel.
Actual Results:
The application had a segmentation fault with the above stack trace.
Expected Results:
The application should quit cleanly.
