#68 process_assignment parser bug

[Peter Parente]

When I run 3.0 alpha1 like so:

epydoc --html --parse-only -o doc_path

I get the following exception about 20% of the way
through the build.

Traceback (most recent call last):

Can you please attach a python source file that generates
this bug when you run epydoc on it? (Use -vv when you run
epydoc to see what file it was processing when it died.)

From your traceback, it looks like the parser created a
documentation object for a function, but did not extract
its argument list for some reason.

Might be resolved in alpha2. Can't tell because I'm getting
a different exception now before this one occurs. Will
provided information as it becomes available.

Thanks for the bug report.

This bug should be fixed in the current subversion
revision.
