https://bugs.edge.launchpad.net/ubuntu/+source/file-roller/+bug/531641

"To reproduce the bug:

1) Create any archive, for example put some files in "archive.tar".
2) In Nautilus, click right on "archive.tar" and remove it (put it in the Trash folder).
3) In Nautilus, go to the Trash folder, find the file "archive.tar" and try to open it with File Roller.

Actual result: not possible to open the archive, File Roller has always this error:

>Une erreur s'est produite durant le chargement de l'archive.
>tar: option requires an argument -- f
>Try `tar --help' or `tar --usage' for more information.

If we restore the archive to its original emplacement, then File Roller can open it without any errors.

Expected result: be able to open the archive with File Roller in the Trash folder."

Thanks,
