dovecot - Sep 2009 - Ubuntu 9.x segmentation fault with vpopmail auth

I've been trying for 24 hours now, to get an IMAP server which will
autenticate off of vpopmail cdb database and the auth module always
segfaults on login.

I'm using vpopmail 5.5.0 only because it is the only version which seems
to create a dynamically linked version of the library.

I tried latest releases dovecot 1.0, 1.1, and 1.2. Also latest mercurial
pulls of 1.1 and 1.2.

Even old versions of courier-imap and courier-authlib do it, but with
these I can try older versions of vpopmail cause they don't require the
dynamically linked version of libvpopmail. So I'm thinking it is
something with Ubuntu 9.04 and pretty much all third party vpopmail
authentication code.

Strangely qmail-pop3d works fine with vchkpwd, just I cannot find any
IMAP server that will work no matter what combination of vpopmail and
version of the IMAP server.

If anyone can figure this out I'd greatly appreciate it.

P.S. I'm going nuts here, trying to get Squirrelmail back up for
customers, but I'm absolutely stuck.

I'm using vpopmail 5.4.17 with dovecot 1.0.10. Have you tried rolling 
your own vpopmail?
