[Nautilus-list] my trash is broke???

[Gary Frederick <gary frederick jsoft com>]

Trash stopped working on directories other than my home directory a few 
weeks ago.

If I select a file and press the Delete key on a file on my home 
directory, it's moved to the trash can.

If I try the same on another directory (eg /usr/ggf/somefile), a message 
comes up telling me that the file can't be moved to Trash and asking if 
I want to delete it immediatly.

How do I set up Nautilus to work with Trash on other directories?

Thanks.

Gary
