Hi All,

I sometimes get this execption to the console on my app. I have not 
really identified what part of my code that is generating the exception 
(I use xml serializers extensively). The app does not crash and I am 
fairly sure that I have wrapped all the parts of my code in a try/catch..

Here is the output to the console.

Serializer could not be generated
System.NullReferenceException: Object reference not set to an instance 
of an object

I am running mono 3.0.1 complied from source on a Fedora Core..

Can any of you guys identify if this is a "bug" in mono or in my code.. 
(and yes I might send something "wrong" into the serializer :-)

Hope you can help..

Cheers

Esben
