Bug 473038

Application: kaffeine (2.0.18)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.4.6-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
further to the problem that the app crashes, other times the app does not crash but complains that:
I am getting from time to time the block of the application with the following 
error message:

Non è stato trovato un dispositivo con impostazioni valide o i permessi di 
accesso sono errati.

Controlla la finestra Configura televisione.

In plain English that is:
a device with suitable settings was not found or the access permissions are 
erroneous. 
Please check within the menu "configure television". 



When you check there all is normal. Closing the app, restarting it, solves it 
immediately. 

I think the behavior is related, but as it does not produce a valid output of debug or a log entry that could make me understand, I can only guess the latter.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kaffeine (kaffeine), signal: Segmentation fault
