Bug#523007: cyrus-sasl2: during a sid recompile the package got built with db4.7 headers -> segfault in sasl2-bin's postinst

[RISKO Gergely]

Package: cyrus-sasl2
Severity: serious
Version: 2.1.22.dfsg1-22

If I recompile the package from source on a up-to-date sid, with
libdb-dev installed, the resulting sasl2-bin's sasldb utilities
(saslpasswd2, sasldblistusers2, sasldbconverter2) segfaults.

I think that the reason is, that the package links with libdb4.6, but
the headers on the system are from libdb4.7-dev in this case.

Removing libdb-dev, installing libdb4.6-dev and changing the builddeps
accordingly of course seems to solve the issue.

risko at bubble:~$ apt-cache madison libdb-dev
 libdb-dev |   4.7.25.3 | http://ftp.ee.debian.org unstable/main Packages

The severity is serious, because during a fresh build the build
succeeds, but the binary is buggy, this can be quite bad e.g. for
porters.
