+
+
+Class being inspected is XmlNodeList.  
+MonoClass.method.count is 5
+MonoClass.methods is null.
+
+Steps to reproduce the problem:
+"make linux" or "mono mcs --unsafe -o codegen.exe -r System.Xml *.cs" in
+gtk-sharp/codegen 
+
+mint throws a NullRefException with a very similar call trace.  No crash on
+windows compiling with mcs, although that may have been with the MS class
+libs System.Xml assembly.  Not sure how to force it to use mono
+System.Xml.dll to make sure.
+
+I'd be happy to track this down more if anyone can give me a nudge in the
+right direction.
