Bug#805310: libsasl2-modules: Annoying message "DIGEST-MD5 common mech free" with svn in systemd journal

[Vincent Lefevre]

Package: libsasl2-modules
Version: 2.1.26.dfsg1-14+b1
Severity: minor

Whenever I use svn, even something like "svn help", a meaningless
message appears in the systemd journal, e.g. journalctl gives:

[...]
Nov 16 21:55:27 zira svn[30840]: DIGEST-MD5 common mech free
Nov 16 21:57:12 zira svn[30987]: DIGEST-MD5 common mech free

[...]

That's annoying. According to dgrep, this message comes from
libsasl2-modules.

This problem already occurred back in 2011:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=631932

but probably for sysvinit machines. It was fixed in 2014 with:

  * Add logcheck snippet to suppress "DIGEST-MD5 common mech free" messages
    (Closes: #732771, #631932).

but this has no effect on my systemd machines. On sysvinit (and systemd)
machines, this message doesn't appear in "/var/log/syslog".
