GstUri parsing is not is not reciprocal for file URIs
Submitted by Marc Leeman
Create a GstUri from a string "file:///home/me/myfile" with gst_uri_from_string
Generate a string from the GstUri (gst_uri_to_string) and you will end up with
"file:/home/my/myfile". As far as I know, the latter is not a valid uri.
Workaround; use file://///home/me/myfile :-/
