KDEInit could not launch </usr/bin/kate>

Steps to reproduce:

- open Dolphin
- click on a text file (Kate will open it)
- click on another text file (Kate will open it in a new tab)
- Go back to Dolphin, and Dolphin is freezed
- close Kate: the error popup will show, and Dolphin can be used again

Status changed to 'Confirmed' because the bug affects multiple users.

I confirm it in Kubuntu 15.04.

I've uploaded a fix to vivid, waiting for approval by the SRU team.
wily will be fixed once 15.04 lands (bug is already fixed upstream).

This bug was fixed in the package kate - 4:15.04.2-0ubuntu1
