User description of above error trace:

closing down application. It looks like it is complaining about the Gemini Ascom Driver. This issue appears to new to 2b81.

Fixed. The underlying problem isn't fixed, but the exception (which is happening in the exception handler itself) should now no longer be a problem, and should now reveal the "true" problem.
