Having the code publically available is one matter.

However, the error showed the following security-related items in any case:

* Python is being used (Risk: a hacker won't try Perl, Ruby, or shell
* Python v2.4.3 is being used (Risk: no need to guess at which cracks
will work...)
* PostgreSQL is being used (Risk: no need to try mySQL hacks....)
* Directory tree: /srv/web/accounts/ (Risk: no need to search out
location of code...)

Certainly, having the code being open is a risk but a calculated one
which is offset by the benefits.

In security, this is known as an "information leak."  The best thing to
do is *hide* all of this information (which also leads to nicer "error"
pages for the user - no tech info, just a "sorry, nasty error: reported
to sysadmin, thanks." or some such.
