Qt 5.6.1 from online installer and GStreamer on (K)Ubuntu 16.10 - MediaPlayer sound issue
Unsolved

Hi all,
I seem to always hit sound issues on Linux when upgrading distributions - no news there I guess :D
However this time the problem seems a bit more Qt specific. I'm using Qt 5.6.1 from the online installers. And sound has worked on Kubuntu 15.10 and 16.04 so far.
I'm using the MediaPlayer QML component imported from QtMultimedia 5.4 to play back an mp3 file.
But I'm getting this error:
GStreamer-CRITICAL **: gst_object_ref_sink: assertion 'GST_IS_OBJECT (object)' failedThis is what I can find of gstreamer related packages installed:
