Bug ID: 462405
Summary: subtitlecomposer crashes when choosing a different
audio stream
Classification: Miscellaneous
Product: unknown
Version: unspecified
Platform: Neon
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: frap...@gmail.com
Target Milestone: ---
Application: subtitlecomposer (0.7.1)
Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 5.15.0-53-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.26
DrKonqi: 5.26.3 [KCrashBackend]
-- Information about the crash:
I don't know which debug symbols I need to install in order to get better stack
traces... for some reason the KDE Crash Handler fails to do so automatically.
In any case, the way to reproduce it is super easy:
1) open a subtitle file for a MKV video with multiple audio streams
2) Right-click the video
3) Under the "Audio Streams" menu, choose the second stream
After this, the program just crashes
The crash can be reproduced every time.
-- Backtrace:
Application: Subtitle Composer (subtitlecomposer), signal: Segmentation fault
