gnome_vfs_find_directory does not locate a newly created trash directory

["Jesse Stockall" <jesse cleverone org>]

I'm trying to monitor volumes for the creation of a .Trash-$USER
directory but the newly created trash directory is not found after a
file is deleted through nautilus.

Steps to reproduce:

Mount a volume with no .Trash-$USER directory
Start a vfs monitor on the volumes activation uri
Delete a file on the volume through nautilus causing the creation of
.Trash-$USER

The monitor picks up the creation of the .Trash-$USER directory but a
subsequent call to gnome_vfs_find_directory (mount_uri,
GNOME_VFS_DIRECTORY_KIND_TRASH,
			                              &trash_uri, FALSE, TRUE, 0) does not
find the trash.

Attached code will start a volume monitor on any drive with no trash
and prints out the result of gnome_vfs_find_directory after
directories are created in the root of the volume. Start it after
mounting a drive with no trash and then delete a file on that volume.
