When starting up Thunderbird with imap-js enabled, I'm getting errors occasionally when selecting folders:

TypeError: can't access property Symbol.iterator, tokens[3] is undefinedImapResponse.jsm:136:40

Keywords: regression

Having a quick glance at the error failure point, it seems risky that there's no error checking on the length of the array in various places:

The code seems to assume that the server will return valid/expected/well formatted responses in all cases.
