This is dolphin 24.02.2 but archlinux applied this patch: https://invent.kde.org/system/dolphin/-/commit/a07f2422.patch

Dolphin segfaults when dragging something over the folder names in the location bar (not the arrows)


STEPS TO REPRODUCE
1. Open dolphin
2. Have the location bar in non-editable mode
3. drag something over a folder name of the bar

OBSERVED RESULT
crash

EXPECTED RESULT
no crash
