Thanks. It's a nice post. But it seems there is no clear solution.
I remember I've caught IOError and ValueError as well.
I think urllib2 needs some unification on exception handling. It
breaks simplicity and this is no good.

But anyway, thanks.

ps Maybe I could contribute to this module but I do not really know
how and where to start.
