Output from a build

When trying to build a MvvmCross example, I got two errors. One was that APK was too big (which I understand) and another was a NullPointerException. The build output is attached in the file:

:  monodroiderror XA0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com. Reason: System.NullReferenceException: Object reference not set to an instance of an object
  Task "ScanAssemblies" execution -- FAILED
  Done building target "_ScanAssemblies" in project "/Users/miha/work/dev/xamarin/MvvmCross-Tutorials/Fragments/FragmentSample.UI.Droid/FragmentSample.UI.Droid.csproj".-- FAILED

Note that the second build (after activating trial) succeeded.
Comment 2 Jonathan Pryor 2014-01-22 10:42:19 UTC
Which MvvmCross sample is this?
Comment 3 Miha Valencic 2014-01-22 10:54:54 UTC
It is Fragments: https://github.com/MvvmCross/MvvmCross-Tutorials/tree/master/Fragments

I'm guessing it is not related to MvvmCross, but to the way XamarinStudio handles the "free version" constraint. I believe the "root" cause of the error is large apk and a version of XS that does not support this (i.e. the free version). After I upgraded to Business Edition (trial) it went through.

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.

It is been more than 3 years so... impossible to reproduce now.
