Bug 372489

Often I wish to view files in kate and attempt to use right click menu to open with then select kate.
However before getting the open with options dolphin crashes.
It seems trying to pick an item in the ópen with´ list (not selecting anything but moving pointer within the resulting list) causes the crash.
Doesnt enter every time but most of the time.
Possibly happens more once 1 file has been opened this way.

definitely crashes before i get to click on ´open with´ option.

On writing this got it to do so with a report error box after running through console ;;;
.....console messages.....
