Error "not on the same filesystem" while deleting "filename..."

["David Holden" <dvdhldn gmail com>]

Hello, I'm getting a Nautilus filemanager error:

 Error "not on the same filesystem" while deleting "filename..." would you like to continue


Basically I'm moving a file from my Desktop to another directory on the file system. 

This other directory is not in my home directory but I own it, its not NFS mounted and I have full permissions on it.


When I try the same with Konqueror or xfe it works fine so I'm baffled.

Anyone have any ideas.

 Thanks,

           Dave.
