Application: dolphin (22.12.3)

Qt Version: 5.15.9

Operating System: Linux 6.2.10-200.fc37.x86_64 x86_64

DrKonqi: 5.27.4 [KCrashBackend]

-- Information about the crash:
When I mount and unencrypt a LUKS-encrypted partition on my SSD, two separate
entries for it appear in Dolphin, one under Devices (where the root partition
and other fstab stuff is) and one under Removable Devices.
Each of these entries seems to work identically and they both have an eject
icon when moused over, but if I eject the one under Devices, the other appears
to stay mounted. If I then eject the one under Removable Devices, Dolphin
crashes. This occurs every time I do so.
When I eject the one under Removable Devices, the removal works perfectly as
expected. Both entries are removed from the Dolphin sidebar, the partitions are
unmounted, and the drive is powered off.

The crash can be reproduced every time.

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