[Gtk-sharp-list] GTK# Application.Init throws NullReferenceException

I have an application in mono C# that we used to interact with from C using
We use the mono JIT interface for C to start the C#.
e.g. mono_runtime_invoke(method, NULL, args, NULL);
This all used to work fine until the upgrade to Ubuntu 7.10 in which we
inherited Mono 1.2.4 up from 126.96.36.199.
Now every time we run this application we get this:
Unhandled Exception: System.NullReferenceException: A null value was found
where an object instance was required.
at Gtk.Application.SetPrgname () [0x00000]
at Gtk.Application.Init () [0x00000]
at GtkHelloWorld.runApp () [0x00000]
at GtkHelloWorld.RunnerMain (Int64 rawPtr, System.String args) [0x00000]
It looks as if GTK dies out at Application.Init :-(
I tried this using just the simple HelloWorld found at
http://www.mono-project.com/GtkSharp:_Hello_World and still get the same
problem. By its self invoking mono HelloWorld.exe it runs no problems,
calling from inside the C JIT interface dies.
As i said this has worked in the past, for a very long time... and just
started playing up.
I'm more than happy to post what ever code anyone might find relevant... I
am hoping someone realizes a change made to the API and might point me in
the direction of a fix.
Thanks in advance
