Interesting. I recently upgraded, and I get the same thing - but I use Maildir. Here's my error: 2009-05-22 17:42:35.797527500 imap-memoryhole.net: dovecot: Panic: IMAP(k...@memoryhole.net): file imap-sync.c: line 439 (cmd_sync_delayed): assertion failed: (client->mailbox != NULL) 2009-05-22 17:42:35.797844500 imap-memoryhole.net: dovecot: Error: IMAP(k...@memoryhole.net): Raw backtrace: imap [0x80d3e80] -> imap [0x80d3eda] -> imap [0x80d378a] -> imap(cmd_sync_delayed+0x292) [0x8066d62] -> imap [0x80609a7] -> imap(client_continue_pending_input+0x86) [0x8060626] -> imap [0x805c097] -> imap(io_loop_handler_run+0x110) [0x80dc0d0] -> imap(io_loop_run+0x28) [0x80daf18] -> imap(main+0x4b1) [0x8068671] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xc8) [0xb7e9bea8] -> imap [0x805a271] 2009-05-22 17:42:35.817635500 imap-memoryhole.net: dovecot: Error: child 28270 (imap) killed with signal 6 (core dumped)

I've done some more tests on that issue and found that I can fix it if I revert commit http://hg.dovecot.org/dovecot-1.1/rev/78ab57f321c8.

Cool!
