System.Argument Exception: [Resource lookup failed - infinite recursion detected. Resource name: Argument_Adding Duplicate__]

I am trying to access a satellite assembly for a custom culture using
Resource Manager. When I use the .getstring method I get the
following error message:

System.Argument Exception: [Resource lookup failed - infinite recursion
detected. Resource name: Argument_Adding Duplicate__]

I can't find anything to help me on the internet except a brief
mention of issues with mscorlib and resource manager. Has anyone come
across this before. I have successfully done something similar in a
simple demo app and now I am trying to make it work in my commercial
app.
