Bug 425753

Application: dolphin (20.08.0)

Qt Version: 5.15.0
Frameworks Version: 5.73.0
Operating System: Linux 5.7.11-1-default x86_64
Windowing system: X11

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

I have inserted a pen drive, then the KDE status bar gave me the option to open one of the partitions of the pen drive. When I clicked that option, a new tab has been created, but dolphin imediately crashed.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
