[PATCH] NULL check in gnome_vfs_uri_to_string()

[Martin Wehner <martin wehner epost de>]

gnome_vfs_uri_to_string() doesn't handle uri == NULL gracefully (certain
segfault). There are some bugs in bugzilla (in various modules) which
crash here. While I agree that the callers need to be fixed too, gnome-
vfs should handle this more defensively.
