  Target Milestone: ---

Application: dragon (22.08.3)
 (Compiled from sources)
Qt Version: 5.15.8
Frameworks Version: 5.99.0
Operating System: Linux 6.1.7 x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
Dragon player crashes immediately after playing short (~5 minutes).

A bit of experimentation suggests that the crash also happens when playing .ogg
files, but not, for example, when playing .avi files. (The AVI file I tried
uses MP3 for its audio stream.)

The crash can be reproduced every time.
