Copying the 'foo' folder from A to B recreates this issue

SUMMARY
If a folder in a location A, containing at least one file, is copied and
attempted to be pasted into a different location B where a folder of the same
name exists, and the user ticks 'Apply to All' in the popup asking how to
handle the folders with identical names, dolphin crashes after around a second.
This is reproducible.

STEPS TO REPRODUCE
1. Have a folder named 'foo' in two locations A and B
2. Have at least one file in folder 'foo' A
3. Copy folder 'foo' A
4. Attempt to paste the folder in the same location 'foo' B exists
5. Tick 'Apply to All' in the popup
6. Wait around a second

OBSERVED RESULT
Dolphin crashes.
The following is logged in the shell

kf.kio.widgets: Could not open file for comparison: "~/repro/A/foo"
zsh: segmentation fault (core dumped)  dolphin


EXPECTED RESULT
Copying works like in other situations
