Bug 440801

Application: amarok (2.9.71)

Qt Version: 5.15.2
Frameworks Version: 5.84.0
Operating System: Linux 5.3.18-59.16-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: "openSUSE Leap 15.3"

-- Information about the crash:
- What I was doing when the application crashed: I selected a search for format:flac. However I have several issues with searching. It almost always crashes. The best change of not crashing is when I type a character, wait 2 sec, type next character etc.

- Custom settings of the application: I don't know if it is related, I use a mariadb database and have a collection of 70.000+ mp3 and flac tracks

If there is anything I can do ... happy to help

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
