Could this be a parsing error with IMAP ALERTs?

I'm currently always around the quota limit, and I just noticed that I  
didn't get quota warnings for a while. This would also explain why  
these errors come and go, because 1) sometimes I'm over, sometimes  
under the limit, and 2) the server doesn't respond each request with  
an ALERT. Example:
