I am frequently receiving the error &quot;Error in menu-bar-update-hook: (error Variable binding depth exceeds maximum-specpdl-size&quot;<br />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)<br /> of 2008-09-05 on vernadsky, modified by Ubuntu.<br /><br />The error occurs when trying to run a shell command of &quot;python &lt;file&gt;&quot; when trying to run the code I am working on. It has become so bad that I&#39;ve had to start running the code in a terminal instead of emacs.<br /><br />Thanks<br /><br />Matt
