Description Caio 2024-09-24 11:21:42 UTC 
Application: plasmashell (6.1.5)

Qt Version: 6.7.2
Frameworks Version: 6.6.0
Operating System: Linux 6.10.10-arch1-1 x86_64
Windowing System: Wayland
Distribution: Arch Linux
DrKonqi: 6.1.5 [CoredumpBackend]

-- Information about the crash:
The bug triggered after a fresh boot when I attached a external ssd drive. The drive use a single btrfs partition on MBR partition scheme, there is an entry configured for this drive on my fstab file to mount a subvolume at a specific path. After recovery from the crash the drive is listed in the plasmoid applet and it mounts the subvolume correctly.

The reporter is unsure if this crash is reproducible.
