Crash on Android when entry bound to integer

In my app, I have an entry that is bound to an Integer. Everything works properly, unless my entry contains a 0 and I try to type another number. As soon as the second number is typed, the app crash. I have the feeling that Xamarin tries to replace the entry by removing the leading 0, then goes into a loop. The problem does not occur on iOS. The leading 0 is removed and it works as expected.
