I've emerged media-video/dvdrip and no entry appeared in my gnome2.10 menu. So I've written my own /usr/share/applications/dvdrip.desktop I think it should be changed at Icon entry because it is just the output of "#locate icon.xpm" and it could (I don't know) be different depending on perl version installed on system.
Created attachment 59771 [details] dvdrip.desktop
fixed in cvs, thanks for reporting
