Bug#730720: cups-browsed: severe memory leak in 1.0.41-1

[Axel Beckert <abe@debian.org>]

Package: cups-browsed
Version: 1.0.41-1
Severity: grave
Justification: consumes all RAM after running for an hour

Dear Maintainer,

updating cups-browsed from 1.0.34-3+b1 to 1.0.41-1 caused the new
cups-browsed process to consume about 1.2 GB of RAM after approximately
6 hours (i.e. between two dinstall runs ;-).

Now it looks even worse: 730 MB RAM usage after just 34 minutes of
running and about 950 MB RAM usage after 47 minutes:

sid:~# date; ps auxwww | fgrep sbin/cups-browsed | fgrep -v grep
Thu Nov 28 17:49:11 CET 2013
root     25233 41.4 70.5 735744 729560 ?       R    17:13  14:57 /usr/sbin/cups-browsed
sid:~# date; ps auxwww | fgrep sbin/cups-browsed | fgrep -v grep
Thu Nov 28 18:00:18 CET 2013
root     25233 41.2 79.6 948960 823632 ?       R    17:13  19:28 /usr/sbin/cups-browsed
sid:~#

Also CPU usage is quite high in average.

Previously cups-browsed didn't have such a peculiar behaviour.

This all happened on a /21 LAN where two Wheezy cups-daemons broadcast
meta-data of 161 printers. (Not sure if this is relevant, but it may
cause this to happen faster than elsewhere with just a few printers.)
