Bug#698640: gvfs-bin: gfvs-trash can not trash on fs that is bind mounted

[basos]

Package: gvfs-bin
Version: 1.12.3-3
Severity: important

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation? 
Trying to trash a file when the home subtree is bind mounted. Both the thunar's
right click->delete and the underlying gfvs-trash <filename> fail

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Using a home bind mount, deleting from the main mount point
Example mount setup
/dev/sda6 on /mnt/imp type ext3 (rw,nosuid,nodev)
/mnt/imp/home on /home type none (rw,bind)

Then the following reproduce the bug
$ cd /mnt/imp
$ touch a
$ gvfs-trash a
Error trashing file: Unable to trash file: Invalid cross-device link

   * What was the outcome of this action?
An error message
   * What outcome did you expect instead?
The file to be trashed 

*** End of the template - remove these lines ***
