Bug ID: 471398
Summary: recently kaffeine crashes when changing channel and
remains a zombie process. Here it crashed with
segfault while stopping reproduction
Classification: Applications
Product: kaffeine
Version: unspecified
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: mche...@kernel.org
Reporter: stakano...@libero.it
Target Milestone: ---
Application: kaffeine (2.0.18)
Qt Version: 5.15.10
Frameworks Version: 5.107.0
Operating System: Linux 6.3.7-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed
DrKonqi: 5.27.6 [KCrashBackend]
-- Information about the crash:
Recently the application is not usable anymore with SAT-cards (here hauppauge)
when you try to change channel.
In these cases you get a crash that leaves a zombie process (waiting for disk)
that requires a complete system restart. I have the doubt that this may have do
with pipewire but this is more an intuition than a knowledge.
Fact is: if you change the channel the app crashes.
If you stop reproduction of the channel, then change the channel, it works.
After the crash Kaffeine is unusable and stays so, until restart of the OS. No
other possibility as to my knowledge exist.
If you enconter the crash, while Kaffeine stays unusuable, VLC does not
encounter a problem and can be used.
If you wish some more output probably related you can refer to the opensuse
bugzilla, here bug:
https://bugzilla.opensuse.org/show_bug.cgi?id=1212461
Please note that I am not sure to a 100% if this crash and the 121246 are
related, but I think they are.
The reporter is unsure if this crash is reproducible.
