If you look at the traceback, it is _very_ strange. The error occurred
in HTMLParser.py line 59, which is part of the HTMLParseError class.
However, it was called from shell.py line 42, which is an exception
handler for a twill.parse.execute_command (or at least is _should_ be).
But based on the traceback, somehow, the _str_() method of
HTMLParseError is being executed instead.
I'm not sure what is going on, but I suspect it may have to do with
Titus's manipulation of the global and local dictionaries in shell.py
line 25. If my suspicion is correct, the "parse" in line 42 is referring
to an HTMLParser object instead of a twill.parse object.
As far as how to proceed, you could step through shell.py right there
(in the do_cmd method) and see what type is being used. Another approach
that might be easier is to put "twill." in front of "parse." on lines
30, 31 and 37 of shell.py. This will make sure that the right "parse" is
being used. If it corrects the problem, then it supports my hypothesis.
