Hi, According to the COPYING file, thunar-vfs is LGPL-licensed. However, <http://git.xfce.org/xfce/thunar-vfs/commit/?id=a85fdcff39376c814fa88c29c274eb06fd4a6606> added two GPL-licensed files (thunar-vfs/exo-hal.[ch]) that seem to be linked in the final library (mostly with thunar-vfs/thunar-vfs-volume-hal.c). I'm afraid this would render thunar-vfs de facto GPL-licensed?
(mmh, except when it's built without hal support ;)
Fixed in 62a90bf
