Unexpected response when logging in to AIM (Captcha Required/Invalid)

[Paul Franklin]

With Windows pidgin/libpurple 2.6.4, I'm getting an unexpected
response when trying to log in to AIM; this worked fine earlier this
evening.  Here's what I see in debug logs:

It doesn't seem like more context should matter, but just in case...
