Thanks for the bug report!

This bug has been reported already, I'll mark it as a duplicate.

Can you reproduce the crash? If yes, can you please provide a Valgrind log of the crash? See https://community.kde.org/Dolphin/FAQ/Crashes . Such a log might tell us what the cause of the crash is, and provide information about how to fix it.
