Debugging mono assembly load error

I am running asp.net/mono on Ubuntu with lighthttpd/fastcgi. Somehow I suspect an assembly reference sneaked in that I cannot track down, and it's causing my application to fail (it works fine on windows under MS.NET).

When I try it under mono, I get:

Failed to create shadow copy (CopyFile).

Description: HTTP 500. Error processing request.

Stack Trace:

System.ExecutionEngineException: Failed to create shadow copy (CopyFile).

Version information: Mono Version: 2.0.50727.1433; ASP.NET Version: 2.0.50727.1433

I am at a loss to how to debug this, as it's not giving me a hint of what assembly it's having problem with.

Any ideas?
