I can confirm that with current Hardy RC1 this bug still persist for Slovak translation. The translation file posted by Yanick solved the problem for me. Could someone push this fix into 8.04 please?
You should go to https://bugs.launchpad.net/ and make sure that there is a workaround on your language. Use the search to find bug reports. If there isn't anything about 'gnome-about' on your language, make a new bug report. And don't forget to mention that Yanick's translation file got it solved.
