Thanks for your report.

That was introduced by:
https://git.gnome.org/browse/gvfs/commit/?id=5d018cd76fb7cfac699602101bc06800569376c9

and have been fixed recently by:
https://git.gnome.org/browse/gvfs/commit/?id=761f226a13b5d46b2f010c8e1c2723f675184be8

I am just going to backport it into the stable branch as well.
