Bug 414549

Application: dragon (19.04.3)

Qt Version: 5.12.5
Frameworks Version: 5.61.0
Operating System: Linux 5.3.11-300.fc31.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

Playing podcasts from gPodder. 
Dragon Player in background. 
Once the file ends, Dragon Player crashes.

This happens sporadically, but always at the end of playing files, whether they are video or audio.

Even playing the same file again does not always trigger this crash, but it is always at the end of a file when it does happen.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dragon Player (dragon), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
