Comment 67 for bug 614742

Ken, could you please review the attached branch and, possibly, release a version of Gwibber with this fix? I don't mean to push on you, but this will allow us to see what kind of errors will people get during authorization.
If the issue is caused by application rate limiting on Facebook side (which is most likely), all workarounds will be useless. Otherwise, the error message will give us more information.
