Hello

I have KDE in Leap 42.2
I have Gnome-subtitles installed and the program was running well until…
I installed Gnome Desktop in Yast>Software>Patterns because I was interested in it.
Since then when I try to use Gnome-subtitles I get this message: Could not play the file *here-video-file* GStreamer encountered a general stream error.
I'll paste terminal output below.
It was working so I have all necessary plugins and codecs.

Solution
Code:
rm ~/.cache/gstreamer-1.0/*
from similar problem doesn't help.

Here is konsole output:
Code:
gnome-subtitles 
Got 6 languages.
