this fails on an Ubuntu installation, running the installed tests. confirmed by a coworker. Where does the 'invalid distro' come from?

this can be avoided when running python with -S, the error comes from a package installed in site-packages.

There's an issue somewhere about allowing certain tests to be run in a tailored python environment (I'm pretty sure it involved test_site but I can't lay my hands on it). It seems like test_pydoc would be another candidate for that capability.

Can our testing gurus shed any light on this?

[encukou]

This is caused by Brailcom's Speech Dispatcher, whose config script ran optparse on import. Apparently it was fixed in their version 0.8.6.

Should we close this as third party or is there something we can do about it?
