I am frequently receiving the error "Error in menu-bar-update-hook: (error Variable binding depth exceeds maximum-specpdl-size" I am working with Python and running Ubuntu 8.10. The version of emacs is GNU Emacs 22.2.1 (i486-pc-linux-gnu, GTK+ Version 2.14.1) of 2008-09-05 on vernadsky, modified by Ubuntu. The error occurs when trying to run a shell command of "python " when trying to run the code I am working on. It has become so bad that I've had to start running the code in a terminal instead of emacs. Thanks Matt
