[Till Kamppeter <1501009@xxxxxxxxxxxxxxxxxx>]

I have tried to reproduce the bug on Ubuntu Wily, Glib 2.46.1, and was
not able to reproduce it (trying both configurations, no dnssd in both
cases and once BrowseRemoteProtocols cups and second,
BrowseLocalProtocols cups). For me cups-browsed always keeps running.

cups-browsed is from the current state of the upstream BZR repository,
but on the CUPS Browsing/Broadcasting support did not change anything
against the version which comes with Wily.

Title:
  g_type_init error when using cups-browsed

Status in cups-filters package in Ubuntu:
  Incomplete

Bug description:
  I'm trying to set up printer browsing using two CUPS servers 2.0.4 and cups-filters 1.0.78 on Ubuntu 12.04 x64.
  Master server has one printer configured, slave has none, and sync over cups-browsed doesn't happen.

  /etc/cups/cups-browsed.conf on the master looks like this:
  BrowseRemoteProtocols none
  BrowseLocalProtocols cups
  AutoShutdown Off

  /etc/cups/cups-browsed.conf on the slave looks like this:
  BrowseRemoteProtocols cups
  BrowseLocalProtocols none
  BrowsePoll printserver-master.acme.com
  AutoShutdown Off

  If I try to run cups-browsed with -d to see what it is going to do, I
  get this output on the slave:

  slave $ sudo /usr/sbin/cups-browsed -d

  Also, it cannot quit:

  cups-browsed: Caught signal 2, shutting down ...
  (process:1877): GLib-CRITICAL **: g_main_loop_quit: assertion `loop != NULL' failed

  Am I doing it wrong? Why these errors appear?
