The "System" menu

[ÐÑÐÐÐÐÐ ÐÐÐÐÐ <ufo users ossm org mk>]

Where do I find and translate the string for the "System" menu on the 
upper GNOME panel?

I want to change the string's translation. I have translated gnome-panel 
100% and there's a msgid string there just after the "Applications" and 
"Places" strings that says "Desktop Enviorment|Desktop". I remember that 
this was the string that I fixed the last time I edited the file for the 
translation of GNOME 2.10 but now when I change it, compile the .po file 
and replace the exsisting .mo file in the latest breezy with the newly 
compiled .mo file I get the thing in English. Everything else is in the 
localized language but only that menu is in English. Is that the right 
string? I can't find a string in any of my .po files with msgid "System" 
and I don't see why I should look for this in another file than in 
gnome-panel.

I've checked this in the bulgarian translation and there it was 
translated âÐÐÑÑÐÐÐâ but I couldn't find that string in the bulgarions 
.po files either.

Help?

Thanks.
