Please describe the problem:
I work with an Ubuntu Breezy distro with an italian interface. I have two
languages installed: english and italian, but I have selected italian as
predefined language.
Normally the nautilus windows have the menu in italian language.
But if I display the file properties of an audio or a video file, the interface
change to english language. Just an example:
For instance in a folder I select the file myvideo.mpg, with right click I
select Properties. Now I look at all the properties panels
(Basic,Emblems,Permissions,Open With,Notes,Audio/Video).
After I close the nautilus window and I reopen a new nautilus window.
Now all the window menu are in english and no more in italian.


Steps to reproduce:
1. open a nautilus window
2. select an audio (wav,ogg,...) or a video (mpg,avi,...) file
3. right click and select "Properties" or choose File/Properties
4. look at all properties panels (Basic,Emblems,...,Notes,Audio/Video)
5. close the properties and nautilus windows and open another nautilus window
--> now all the menu are in english


Actual results:
The nautilus window menu are all in english and no more in italian

Expected results:
The nautilus window menu have to remain in italian because this is my predefined
language

Does this happen every time?
yes

Other information:
To resolve the problem for now I use the system monitor for terminate the
nautilus process.
When nautilus restart, the window menu are again in italian.
