I have exactly same problem! This is how to track it: You must have at least ONE partition, that is not listed in /etc/fstab or any REMOVABLE disk. Insert disk or pick unmounted partition and access it, entering password. Create a file. Delete a file with "Remove" option.
The directory .Trash is created on current disk/partition (correct behavior). However, the Trash icon does not change from empty to full. If you try to empty trash, it won't be available, because Thunar thinks its empty. If you go inside .Trash however, you will find your deleted file. I confirm this!
