Bug#995023: gnome-keyring fails on home directory provided by sshfs

The proposed patch here is working around sshfs being incompatible with
the assumptions of a previous workaround for a different filesystem
bug.  I don't think this change should be applied in Debian until its
implications are understood, which is better discussed upstream than here.

Tagging this "- patch" to reflect that the patch is not ready to apply.
