Bug 428889

Application: elisa (20.08.2)

Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.9.1-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

1. Open Elisa and specify music files path
2. Wait several minutes (maybe 5 to 10 or so?)
3. No music files display, search icon still turning
4. When no music files listed yet in Elisa, go to the Path section
5. When changing to the Music path, Elisa crashes

The crash can be reproduced every time.

-- Backtrace:
Application: Elisa (elisa), signal: Segmentation fault
