Freeze break request: gvfs, afc backend

[Bastien Nocera <hadess hadess net>]

Hello,

2 small commits for the gvfs-afc backend:
https://bugzilla.gnome.org/show_bug.cgi?id=613588
and
https://bugzilla.gnome.org/show_bug.cgi?id=591009

One compilation fix, and the other to make the experience with iPhones
and iPod touches better.

Both tested successfully.

Cheers
