[Python.NET] (no subject)

[Aleks Berland]

Hi All,
I'm new to the list and to Python.NET

I am running the latest from Git, on Mono in Ubuntu 14.04.

I am working with NHibernate Database Configuration code,
I am experiencing problems trying to explicitly state generic
parameter (NHSearch)  so the C# strong type syntax make it possible infer
from NHSearch.Instance.

The offending line in pythonnet is:

db_adapter =
DatabaseAdapter.Configure.DatabaseConfiguration(conn_sql).SearchProvider[NHSearch](NHSearch.Instance)


And I get this back:


Unhandled Exception:
System.ArgumentException: GCHandle value cannot be zero
  at System.Runtime.InteropServices.GCHandle.op_Explicit (IntPtr value)

Not sure how/where to start to debug this. Any tips would be helpful!
I would be happy to give more details if needed of course, but I am not
sure what will help at this stage, so let me know.

Regards,
