Simple Mail 2.80.1 doesn't work under the now public Firefox 7.

Errorcode (German):
Fehler: Simple Mail: [imap.googlemail.com:993,ssl]: Ungültige Antwort: 7 BAD Could not parse command
Quelldatei: chrome://simplemail/content/utils.js
Zeile: 178

What means sth. like:
Error: Simple Mail: [imap.googlemail.com:993,ssl]: Invalid Response: 7 BAD Could not parse command
Source: chrome://simplemail/content/utils.js
Line: 178

Waiting for a fast fix,
as its not doing anything,
and i don't want to switch to an external email tool.

P.S.: I don't know how important it is,
