FileBackend failing base path not a bytestring

[chopfitzroy]

When I try to use the mopidy file browser ([Files] in ncmpcpp) I get the following error:

ERROR    FileBackend backend caused an exception.
Traceback (most recent call last):

ValueError: base_path is not a bytestring

From the few issues I could find it I believe it is to do with system file encodings ascii vs unicode? If there is anything I can do to further debug this let me know.

I am on debian running Mopidy 2.2.1

I've reproduced this and have a fix that I'll push as soon as my ISP fixes my Internet connection.

Thanks for reporting!
