When/if you ever get this error, can you please expand the 'Details' view so we can actually see what has gone wrong. Can you also attach the MonoDevelop.log file found in ~/Library/Logs/MonoDevelop-2.8/MonoDevelop.log from the session where MonoDevelop crashed.

Can you move the directory ~/Library/Caches/MonoDevelop-2.8 to ~/Library/Caches/MonoDevelop-2.8_backup while MonoDevelop is not running and then see if it will update correctly the next time you check for updates.
If this does work correctly, I will need to grab a couple of files from the original directory, so please find me on IRC and i'll figure out which ones I need that way.
I committed a fix for this a few weeks ago.
Today, We have checked this issue with following builds:
XS 4.0.8(build 2)
Xamarin studio is launching successfully, without throwing any exception. Hence marking this as Verified fixed.
