owl_function_error: Bail out early in the case of recursive errors. owl_function_adminmsg triggers a lot of code, and so it is possible that whatever caused an error will also cause owl_function_adminmsg to error out. Watch for recursive calls to owl_function_error, and bail out early to prevent infinite looping.
