Alright, so I figured out that the problem is broken mailers sending  
e-mails that don't conform to RFC2047.  If you access an IMAP folder  
for the MBX file shown below, you'll see a "Fatal error: Invalid  
argument" tooltip shown in the IMP UI.

=== End of MBX file ====

The problem is the umlaut-a (ä) in the "To:" line.  If the 'ä' is  
replaced with an 'a' then the message-index loads fine.

If the mailbox passes some number of messages, then the "Invalid  
Argument" tooltip isn't shown anymore.  At that point, the only way to  
identify a failure is the "Uncaught TypeError: Cannot set property  
'VP_rownum' of undefined " visible in the JS console.
