Description RJVB 2017-01-07 21:51:08 UTC 
Application: kate (16.12.0)
 (Compiled from sources)
Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

-- Information about the crash:
- What I was doing when the application crashed:
* open a document
* activate the filesystem browser
* use a shortcut to trigger the "Show Active" action (I use Command+<, that is, Command+Shift+,)
* reactivate the filesystem browser
* quit Kate

Quitting will pause while some child process (the Konsole plugin shell?) is not responding to SIGHUP, and then this crash happens.

- Unusual behaviour I noticed:
After the initial opening of the window & document (if given on the commandline), Kate takes long seconds "beachballing" before it becomes responsive. This has been the case for a couple of versions now.

The crash can be reproduced every time.
