Bug#527161: sasl2-bin tools segfault after upgrading to 2.1.22.dfsg1-23+b1

[Daan Willems]

Package: sasl2-bin
Version: 2.1.22.dfsg1-23+b1
Severity: grave
Justification: renders package unusable

tools from the sasl2-bin package are unusable due to segfaulting after upgrading to 2.1.22.dfsg1-23+b1
example:

# sasldblistusers2
DB->get: method not permitted before handle's open method
: Successful return: 0

# saslpasswd2 -c test
: Successful return: 0
DB->fd: method not permitted before handle's open method
Segmentation fault

from postfix log when trying to do sasl authorisation:
postfix/smtpd[26673]: connect from caladan.homelan.org[192.168.0.2]
postfix/smtpd[26673]: warning: SASL authentication failure: error fetching from sasldb: Invalid argument
postfix/master[25867]: warning: process /usr/lib/postfix/smtpd pid 26673 killed by signal 11
