SUMMARY
In Dolphin > Configure > General > Previews, if uncheck a checkbox, e.g., Apple
Keynote Documents, the box becomes unchecked, but after clicking OK, a message
box appears that kioslave5 closed unexpectedly. When I go back to the Configure
option, the box is checked again. Apparently, the attempt to change a box to
unchecked and save it is unsuccessful.

***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

STEPS TO REPRODUCE

2.  Try unchecking a box that was previously checked.
3.  Press OK

OBSERVED RESULT
1. message box appears that kioslave5 closed unexpectedly
2. reopening configure window shows that box is still checked.
