I finished stripping down my engine last night to find the right hand main bearing had given up the ghost and wondered if this was a common problem or if it was caused by lack of use and oil draining away from that bearing.

Bear in mind that most cranks haven't been rebuilt yet, and that all original cranks are at least 15 years old, and some 24 years old!

Your average MC21 crank had been in service for 20 years now... a worn out right hand main can hardly be classed as a "common" problem, although that bearing is undoubtedly under the most duress.
