Bug ID: 468100
Summary: Kaffeine crashes under the premise: one channel
reproduces (paused or not) and another channel change
is forced by programmed registration.
Classification: Applications
Product: kaffeine
Version: unspecified
Platform: openSUSE
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: 5.15.8
Frameworks Version: 5.104.0
Operating System: Linux 6.2.8-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed
DrKonqi: 5.27.3 [KCrashBackend]
-- Information about the crash:
this is actually provocatable quite easily if you have a sat card.
what a channel that is on one Sat bouquet.
Put it in pause or let it run, does not really matter.
Put a second channel at a certain hour in registration. It shall be on another
bouquet. So in order to register it, the card is forced to change channel.
When this happens:
the play simbol is lighted, the stop simbol is greyed out.
When you wish to watch the movie that is registed and select the channel the
crash is induced. This because to see it either you click on the channel in use
and this might induce the crash, or because you click on the play simbol and
then the app crashes.
In a certain percentage of cases (about 10%) you may have that the app survives
after the first selection. You sill then be able to what the movie but the app
may be still unstable because when stopping the reproduction (leaving it
however open to register in background) it still may crash.
This is actually a very long standing bug (can be found since at least two
years) but this is the first time I am getting a backtrace nicely.
The reporter is unsure if this crash is reproducible.
