Bug ID: 377470
Summary: KDevelop sometimes crashes when right-clicking the
toolbar
Product: kdevelop
Version: 5.0.80
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: asusylv...@hotmail.fr
Target Milestone: ---
Application: kdevelop (5.0.80)
Qt Version: 5.8.0
Frameworks Version: 5.31.0
Operating System: Linux 4.10.1-1-ck x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Right-clicking the toolbar (couldn't reproduce with another UI element). I
could make it crash right-clicking the "new file" button, but I remember having
it crash right-clicking a separator.
I didn't find a way to reproduce the crash accurately - thread race? It seems
to rely on some factor I haven't figured out.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Illegal instruction
Using host libthread_db library "/usr/lib/libthread_db.so.1".
