Frameworks Version: 5.32.0
Operating System: Linux 4.14.16-server-1.mga6 x86_64

-- Information about the crash:
I have opened twi Dolphin windows.
I have activated the "view hidden files" in both windows.
I closed one of the two windows.
then crash!

I have also noticed that, several times after Dolphin crash, Dolphin is
consuming lot of CPU,  even when I have closed Dolphin window. I have noticed
that by running KSysguard

The crash can be reproduced sometimes.
