Can not create tar.7z archives.

[ceed <cdposter-usenet yahoo com>]

Hi,

I am not sure this is a Gnome problem, but anyway: When I right click on a  
file in Nautilus (v 2.30.1) and select "Compress" and tar.7z as format  
nothing happens. No archive is created. I have 7zip full installed on my  
system so that's not the problem. I can create all the other archive  
formats from the context menu without problem. I can also create both tar  
and 7z archives separately. I am currently running Linux Mint 9 x64, but  
had the same problem on Mint 8 x64. Any idea what may be wrong?
