Bug 404273

Application: dragon (18.12.2)

Qt Version: 5.12.1
Frameworks Version: 5.55.0
Operating System: Linux 4.20.7-zen1-1-zen x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I had just simply tried to open some audio files and the player seems to crash almost every time I open them. They were .wav files, I have all the codecs and Dragon will play them flawlessly if it sucessfully starts without crashing.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dragon Player (dragon), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
