I did some more digging and here's the actual error that it fails with:
Apr 23 09:28:21 batman.rutgers.edu IMAP(kmech): : [ID 107833 mail.crit]
Panic: file squat-trie.c: line 441: assertion failed:
(!node->have_sequential)

Sorry for sending this in multiple emails, I'm trying to help someone
debug it and I'm not getting the info all at once.
