[MonoTouch] Strange issue iOS5.1 vs Environment.SpecialFolder.Personal

[Sebastien Pouliot]

Hello Nic,

It was in the release notes [1]. However, at the time, the condition
was not reproducable by anyone (just an error in a user's application
log).

I suspect most people testing the iOS 5.1 beta releases where using
provisioned devices where the error does not occur. In retrospect we
were lucky for that (single) report.
