Please include your full build logs, test case (to reproduce) and all version informations.

The easiest way to get exact version information is to use the 
"Xamarin Studio" menu, "About Xamarin Studio" item, "Show Details" 
button and copy/paste the version informations (you can use the 
"Copy Information" button).

Hi Vincent,

This crash is reported in Xamarin insights from live users, it is very difficult to reproduce.
can you give a rough guess where the problem might be?
