(imap) killed with signal 6 (core dumps disabled)

1.2.7, Linux/Debian Lenny, amd64, NFS spool and index.

Seems to be happing every few minutes, probably every time they check  
mail. The command they're sending:

A002 STATUS "INBOX" (MESSAGES UNSEEN RECENT)

Output doesnt show any result, only their login:

A001 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID
