SUMMARY *** When copying identically named files from one directory to another, choosing the "overwrite" option causes Dolphin to crash. Downgrading kio from 5.110.0-1 to 5.109.0-2 resolves the issue. *** STEPS TO REPRODUCE 1. mkdir test1 test2 2. touch test1/file{1..9}.txt test2/file{1..9}.txt 3. In Dolphin, copy the nine files out of test1 and paste to test2 4. When prompted to overwrite, rename, or skip, choose overwrite. OBSERVED RESULT Dolphin reliably dumps core. Downgrading kio from 5.110.0-1 to 5.109.0-2 resolves the issue. EXPECTED RESULT The expected result would be the application succeeds in overwriting the files without crashing.
