Description rlaggren 2016-04-26 01:32:16 UTC 
Create new encrypted file from sample small text file.  Run Kate, open new file. Kate dies,  Complete output when kate is started in a terminal:

Phonon::GStreamer::Backend: Failed to initialize GStreamer
QTimeLine::start: already running
Segmentation fault

"About kate" info window shows:

Version 15.12.3
Using:
KDE Frameworks 5.20.0
Qt 5.5.1 (built against 5.5.1)
The xcb windowing system

Reproducible: Always

Steps to Reproduce:
1.Create new encrypted file from sample small text file.  
2.Run Kate,
3. open new file

Actual Results:  
kate dies. When running from a terminal, output says

"Phonon::GStreamer::Backend: Failed to initialize GStreamer
QTimeLine::start: already running
Segmentation fault
"

Expected Results:  
kate displays open file, probably read only, and complains about a binary file

Tried a couple of small gpg files. Same result. Kate has not shown this behavior w/any other files. Normally I use kate to review any/all files, some very large, binary has never been a problem. But I only use kate two or three times a week for this purpose. Not a kate power user.
