Thanks for the bug report!

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.
Comment 2 Syam 2015-03-20 01:52:59 UTC 
I have not encountered this crash again. And I'm not able to reproduce it either.
Will update this report if this happens again.
