Mono version 1.9 (/trunk/ r95154)

In an ASP.NET 2.0 Application i'm using Activator.CreateInstance() to load a
instance of IDbConnection from Npgsql.

Npgsql exist in Mono's GAC and a own copy of it in my /bin folder.
It works well mos of the time.

But from time to time i get the following exception:

System.ApplicationException: Unable to load assembly 'Npgsql' containing
implementation type 'Npgsql.NpgsqlConnection'. --->
System.IO.FileNotFoundException: Could not load file or assembly 'Npgsql' or
one of its dependencies. The system cannot find the file specified.

I've no idea how to reproduce this.
I've never had this exception with: version 1.2.6 (/trunk/ r92431)
