Comment 1 Christoph Feck 2017-11-09 00:54:28 UTC 
The backtrace says you clicked the 'eject' (or 'unmount') menu entry. Not that it should crash when selecting this entry, but it might help to reproduce the issue.
Comment 2 Justin Zobel 2020-10-25 00:44:19 UTC 
Can you please confirm if this still happens on a recent Dolphin version.
