This bug can take many forms, and will happen randomly, but the most common way people notice it is when they end up on a form to view/edit a Menu entry instead of the resource they clicked on.
The problem seems to stem from a bug in CherryPy, as indicated by Christophe Combelles's analysis (see comments #58 and later).
- upgrade to a recent version of branch 3.1.X of CherryPy, (3.2+ should be avoided as it may cause other issues, 3.1.2 contains the bug), for example using this command:
pip install hg+http://bitbucket.org/cherrypy/cherrypy@4c7d91d0b329#egg=cherrypy
- or if proxying with Apache, add "SetEnv proxy-nokeepalive 1" in your Apache virtualhosts, to disable the use of HTTP/1.1 persistent connections and prevent the CherryPy bug
- or add this in your web client config: "server.socket_timeout = 60" (60 is arbitrary, any large value may work), to allow all waiting requests to complete before allowing CherryPy to timeout the persistent connections

It happend since a moment, and I don't know why. Simetimes it works, sometime it doesn't. If can't reproduce the bug, try to restart your browser, and directly go the modules list.
Note: It happend will other tree views, not only modules.
