System.ArgumentException : Duplicate dynamic module name within an assembly in Nhibernate 3.3.0.4000

I'm having an issue I cannot reproduce and I cannot track down. It happens for one client, in one area of the site, on one environment only.

System.ArgumentException : Duplicate dynamic module name within an assembly.

StackTrace

at System.Reflection.Emit.AssemblyBuilderData.CheckNameConflict(String strNewModuleName) at System.Reflection.Emit.AssemblyBuilder.DefineDynamicModuleInternalNoLock(String name, Boolean emitSymbolInfo, StackCrawlMark& stackMark) at

There are numerous posts saying that it's a problem with Castle.DynamicProxy but the version of nhibernate I am using does not need/use the castle library. I am using NuGet for my FluentNHibernate reference and everything is up to date.

I checked the bin on the server and there is no castle dll. The nhibernate dll is the correct version.

This is a race condition bug in NHibernate, see https://nhibernate.jira.com/browse/NH-3172.

It is fixed in 3.3.1GA which should be available for download within a few hours.
