[Christian Juner <1442649@xxxxxxxxxxxxxxxxxx>]

The trouble seems to stem from glib's way of deleting files being
different to the way gvfs tries to locate trash directories.

glib's gio/glocalfile.c contains the find_mountpoint_for function which
is used to determine the device's root directory as location to put the
.Trash-<uid> directory. It looks at the stat(2) st_dev value ("device
number"). btrfs gives each subvolume a different device number.

gvfs's trashlib searches for trash directories based on mount points
determined by getmntent_r(2).

I do not know how to fix it in general. A fix for btrfs might be to
search for all subvolumes of a btrfs mount point returned by
getmntent_r(2). Not sure if you can listen to new subvolumes being
created after the initial search, though (maybe inotify can?).
