500 error on TestDriven

[Ken Kuhlman]

It's sort of ironic, but the page on test driven development:

http://docudo.webfactional.com/current/TestDriven
is producing the stack trace below.


Good job getting Docudo up and running again.

IOError: [Errno 5] Input/output error

[Kevin Horn]

Thanks Ken!

I noticed this as well, but haven't had time to look into it yet.  I'll get to it as soon as I can.  In the meantime, if anyone else has any ideas as to what's causing this, feel free to post them here.

I still haven't had time to look into this properly, but:
- it's coming from docutils
- its an IOError
- its choking on a print statement

print >>self.stream
, msgtext

My guess is that self.stream isn't valid...but I haven't dug through the docutils source to figure anything further out, so it _is_ only a guess.

Suggestions welcome.

OK, digging into docutils a little deeper...it appears that the page itself has markup errors in it (or is causing docutils to throw some other error).  When docutils tries to print this error, it can't (for some reason) and thus the traceback we see, rather than an error message.

Opening a ticket in trac... #31
