Bug#894427: parley: Sound does not play in editor

[Svetlana Tkachenko <svetlana@members.fsf.org>]

Package: parley
Version: 4:17.08.3-1
Severity: important

Dear Maintainer,

I started editing a new dictionary whose filename is '1',
clicked view > sound,
and specified path 1_files/File-en-wordname.ogg'
When I clicked play, I saw error message 

GStreamer; Unable to pause - "file:///1_files/File:En-us-wordname.ogg"
GStreamer; Unable to pause - "file:///1_files/File:En-us-wordname.ogg"
Error: "Resource not found"

and there was no sound. I had expected the sound to be played. This is because of its confusion about the relative file path I think.
