Application: dolphin (22.12.1)

Qt Version: 5.15.8
Frameworks Version: 5.101.0
Operating System: Linux 6.1.4-arch1-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
-have 2 external drives connected
-copy (many files) from 1 external to the other external in 2 seperate copy tasks
-pause 1 task (dont pause the other)
-disconnect both external drives (by accident loss of power, without proper umount, etc...)
-reconnect both external drives (also mount again)
-task 2 (the one not paused) says there was an error, but gives option to retry/skip/cancel... if picked retry, the copying task continues with no problems
-task 1 (the one paused) reports no error with copying at first, but when resumed from pause, it concludes the copy task with a crash (not completing the copying)

expected result:
-task 1 when resumed from pause also restarts the copying where it was last paused, or at least reports similiar error to task 2 (that was not paused) with option to continue the copy task

(I know the situation is very edgy and I'd never even stumble upon it if it wasn't for an accident, but if active copy task can be recovered (was a nice surprise), then the paused should also have same logic)

The reporter is unsure if this crash is reproducible.
