Comment 8 for bug 648930

I just checked out 0.20. I'm still sick.
Putting custom folders ( [Gmail]/ ) doesn't prevent from starting( which strangely was an issue 0.19).
That Archive folder that causes the problem( at least for two of us here) is after installation as default one for test account. It's not present in every gmail account it seems (my guess is it's either created by email clients since most of them have archive option or localization issue). ARCHIVE is certainly present in my Postbox and Thunderbird clients but not directly on gmail account.

Maybe parsing reported folders would be a good feature? Just so make it dumb/confusion proof.
