Xamarin Android Mvvmcross app crashed on MvxBootstrapRunner

Sometimes (1/7) my app crashes on android 4.0.4 on splash screen with SIGSEGV error in MvxBootstrapRunner class in stacktrace, and then can start after 'force stop' only. If application crashed once endless splash screen will be displayed every next time (before force stop). MvvmCross version 3.5.1
