Issue desmotration code.

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US)
AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.224 Safari/534.10

The code attached as test sample which links against Common.Logging.dll 2.0
fails, while compiling against Common.Logging.dll 1.2.0 works fine.

Looks like some kind of dependency solving problem, as one of the referenced
assemblies (NServiceBus.Core.dll) was compiled against Common.Logging.dll
1.2.0.. However, CL 2.0 is binary compatible with 1.2, so it is supposed to
work, and in fact, on MS side, compilation works against both libraries without
and problem.

The actual compiler error is:

Internal compiler error at test.cs(20,21):: exception caught while emitting
MethodBuilder [TestClass::SomeMethod]

System.Collections.Generic.List`1[NServiceBus.Utils.WorkerThread]:_items

Reproducible: Always

Steps to Reproduce:
1. Download attached test case ;)
2. Decompress..
3. Execute ./run.sh
4. See compiler error..
Actual Results:  
Compilation fails..

Expected Results:  
Code compiled ok.

I've tested it on mono 2.8.2/linux and 2.10-preview/win32, failing in both
cases.
