Corbett,

Everything looks okay to me, and I just did a fresh install, as root, from the 1.0b5 tarball. Then I created a dummy list and had no problem viewing the list-of-lists and the specific list info page. Note that I am running this in a Solaris 2.6 system, what OS are you using? We've had one other report of something similar happening on Linux (so I wonder if some OS problem could happening).

Since I can't reproduce the problem on my end, I'm going to need your help. We have trace through the driver script to see where it's crapping out. Here's a version that does some very simple print-style tracing to /tmp/mailman.log. Can you substitute this for scripts/driver and see if it gives you a clue as to what is failing?

# This standard driver script is used to run CGI programs, wrapped in code # that catches errors, and displays them as HTML. This guarantees that # (almost) any problems in the Mailman software doesn't result in a Web server # error. It is much more helpful to generate and show a traceback, which the # user could send to the administrator, than to display a server error and # have to trudge through server logs.

# Note: this isn't 100% perfect! Here are some things that can go wrong that # are not caught and reported as traceback-containing HTML: # # - This file could contain a syntax error. In that case, you would indeed # get a Web server error since this file wouldn't even compile, and there's # no way to catch that. # # - The sys module could be royally screwed. Either we couldn't import it, or # it didn't have a sys.stderr attribute. Both those would indicate serious # problems in the Python installation. These won't generate Web server # errors, but neither will they give meaningful tracebacks. # # - We couldn't import the traceback module, or traceback.print_exc() # failed. Same diagnosis and effect as with sys being broken. # # I consider all these pretty unlikely. Note that it is also possible that # the environment variables wouldn't be printed, perhaps because os couldn't # be imported or there was some problem with os.environ. Again, not likely.

Mailman experienced a very low level failure and could not even generate a useful traceback. Please report this to the Mailman administrator at this site. """
