[Mono-dev] Difference on reference search between mono 2.4.2 and mono 2.4.3

Hi,

I was using with success a web application on Centos with mono 2.4.2 
compiled from source.
To try the new version I downloaded the Mono 2.4.3 Virtual machine, I 
copied my web application to the new server and it gives an error 
cause Crystal Reports dll are missing.
Those dll are referenced inside other assemblies but not used.
It sounds strange to me that 2.4.2 doesn't complain about that and 
2.4.3 gives an error.

As I cannot remove the reference, where is the difference between the 
two machines? It's due to mono version or to some different 
configuration or compilation option?

The error displayed is:

System.Reflection.ReflectionTypeLoadException: The classes in the 
module cannot be loaded.
