[Dovecot] Dovecot Assertion on mail server with POP3 and LDAP authentication

Running two Fedora 6 systems with all the latest updates as of a week
ago. One system is the mail server (sendmail, dovecot), the other is
the master (open)LDAP server with the mail server running a slave LDAP
instance.
The problem I'm having is the client pop3 users are frequently being
told their passwords aren't correct by their email clients (Outlook,
Eudora). They try again, a couple times and eventually it works. I've
seen it on my own account and when I test their accounts, occasionally
it just doesn't take the password. I've only had this trouble since I
implemented the LDAP authentication.
Checking through the server maillog, I see the following entry:
Apr 4 08:44:38 msi2 dovecot: auth(default): dovecot-auth:
../../../libraries/liblber/io.c:491: ber_get_next: Assertion
`ber->ber_buf == ((void *)0)' failed.
Apr 4 08:44:38 msi2 dovecot: auth(default):
pam(secretuser,192.168.0.200): Child process died
Apr 4 08:44:38 msi2 dovecot: auth(default): PAM: Child 14564 died with
signal 6
Apr 4 08:44:38 msi2 dovecot: pop3-login: Aborted login:
user=<secretuser>, method=PLAIN, rip=192.168.0.200, lip=192.168.0.11
This seems to point out that dovecot is the problem, but again, I didn't
have this trouble until I implemented the LDAP authentication. So my
question is, anyone know a solution? If not, anyone got a suggestion of
where I should look for more clues or support? Or any suggestions at all?
Thanks for any help.
Following is the dovecot version and configuration
