Bug 442583

Application: amarok (2.9.71)

Qt Version: 5.15.2
Frameworks Version: 5.85.0
Operating System: Linux 5.14.1-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.5
Distribution: "openSUSE Tumbleweed"

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

Attempted to navigate back in the sidebar from a file listing, and any of the options (either the home icon, >, or Files, causes a crash. I noticed that the breadcrumbs only show "[home] > Files", and not the path shown in the file browser (not sure if related, but probably best to mention it).

The crash can be reproduced every time.

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