dovecot - Oct 2004 - errors in logfile

I just upgraded to -test47 from 0.99.11-test4, and am getting a bunch of
these messages in the logfile:

dovecot: Oct 14 07:30:21 Info: imap-login: Login: andrew [64.36.1.74]
dovecot: Oct 14 07:30:22 Error: IMAP(andrew): sigaction(SIGRTMIN) failed:
Invalid argument
dovecot: Oct 14 07:30:22 Error: IMAP(andrew): fcntl(F_SETSIG) failed: Invalid
argument
dovecot: Oct 14 07:30:22 Error: IMAP(andrew): read(event_pipe) failed: Is a
directory
dovecot: Oct 14 07:30:22 Error: child 7047 (imap) returned error 89
dovecot: Oct 14 07:30:22 Error: child 6631 (auth) killed with signal 11

Any ideas? How can I get more information about what's happening there?

Thanks.

This is Linux? What kernel version? What distribution? Any special 
kernel patches?

gdb backtrace from this would help. Do you see a core file in 
/var/run/dovecot/ (or /usr/local/var/run/dovecot) directory?

Is this some sort of trick question or what?
