When using Dolphin search functionality and right-clicking or trying to open files Dolphin crashes everytime. Reproducible with new user account also.

Reproducible: Always

Steps to Reproduce:
1. Open Dolphin and search for some existing file (CTRL+F)
2. Try to right click or open directly one of the result files.
3. Dolphin will crash
Actual Results:  
Dolphin Crashes. Browsing file with dolphin without using search functionality works fine.

Expected Results:  
Context menu or file should open.

Application: Dolphin (kdeinit4), signal: Segmentation fault
