Handle erroneous html_parser exception on py2.6.

[ralphbean]

This should fix #15 and consequently fedora-infra/fedora-tagger#107.

(It raises the exception that we catch when it runs into an email address surrounded in <> delimiters.)

It looks fine but seems to be doing two different things, won't that create two different behavior?

It will. If it succeeds without exception, it will strip any html tags from the text. If it raises an exception, the html tags will still be included (but I'd rather have that than a traceback).
