Thank you for taking the time to submit the bug. We are unable to reproduce this issue. Please attach a reproduction to the bug by starting with a clean Xamarin.Android project and adding just the code necessary to demonstrate the issue. Looking through the log, I see this which might point to the area to look at in the application code:
