[Mono-dev] System.IO.Packaging throws NullReferenceExeption

[Alan]

Hi,

For every testcase which fails, could you create a bug report on
http://bugzilla.xamarin.com, attach the testcase and assign it to "
alan at xamarin.com". I will look at them when I get a chance and fix the
underlying issues where possible. If you could also attach the resulting
'out.zip' created from the microsoft framework, that would make it faster
for me to ensure things are generated correctly.

Thanks!
Alan
