Comment 8 for bug 1449790

This comment I made in one of the duplicates and should probably be shown on the main bug :-)

So trying this locally with gst-launch

This works correctly
$ gst-launch-1.0 -v playbin uri=file:///home/andy/Music/INXS/The%20Greatest%20Hits/01%20-%20Mystify%23.flac

But this fails
$ gst-launch-1.0 -v playbin uri="file:///home/andy/Music/INXS/The Greatest Hits/01 - Mystify#.flac"

I suspect this latter case is occurring and either we or media-hub need to be encoding the URI correctly.
