hmmm so the conslusion is that Win7 is better than WinXP

of course just kidding
OK, but more seriously - does this problem concerns About command only? What if you run any other command (without any further launch or debugging), close and just exit VS - does crash happen like in case of 'About' dialog?
Anyway it seems to me, that we will have to prepare some better diagnostics. But formerly we will hunt bug with context menu in German VS - we suspect that WinGDB option is invisible due to version other than English (in your case German).
Es wird sehr interessant VS in Deutsch zu sehen

Kind regards,
