important xscreensaver problem for pt_BR

[Evandro Fernandes Giovanini]

Hi,

the latest xscreensaver update caused some problems in the pt_BR
translation of the xscreensaver desktop file. I added comments to
http://bugzilla.ubuntu.com/show_bug.cgi?id=16448.

This is a trivial fix, but a must-fix for breezy, as the menu looks
completely unprofessional right now. I'm CCing the devel list to make
sure it's not too late. :)

Thanks,
Evandro
