can't fetch mail

Good afternoon all,

A new problem just cropped up for me this morning.  It used to be when  
I "Get new mail" I'd get a popup showing each of the servers from which  
I POP3 fetch mail, showing the status and progrss of each.  Now, I just  
get a popup "Checking mail" but it doesn't show any of the servers, and  
only stays up for less than a second.  I can use my IMAP connection to  
see that I do have new mail.  Using $G_MESSAGES_DEBUG="mbox-pop3"  
produces no output.  It seems like it's just silently failing to even  
try to do a pop3 fetch.

I just recompiled from git head and the behavior didn't change.  I  
don't see anything relevant in dmeg or /var/log nor in console output.

Any suggestions for further troubleshooting?

Thanks.

Jack
