I am guessing it happen when using your plugin but does not happen when not using your plugin, correct?

Run the plugin in debug and catch the exception, what is the last actions done?

If you have not tried this before see the notes in Plug-in Development -Getting Started - “Start Debugging from Visual Studio This Way:”
