Well, I have no experience with imap_authenticate, but you need to  
look at this line 52 in the plugin's code to see what is the 'nil' and  
then find where that gets set.  Chances are there's a condition that's  
not being properly checked for and the connection is never made; then  
when some later error happens, the cleanup to disconnect is getting  
called on the never-successfully opened instance.
