[Bug 946718] Re: backend_helper.py crashed with RuntimeError in add_signal_receiver(): To make asynchronous calls, receive signals or export objects, D-Bus connections must be attached to a main loop by passing mainloop=... to the constructor or calling dbus.set_default_main_loop(...)

Hello Aubrey, or anyone else affected,

Accepted update-notifier into precise-proposed. The package will build
now and be available at http://launchpad.net/ubuntu/+source/update-
notifier/0.119ubuntu8.6 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Impact]
  This is one of the top-reported bugs on error.ubuntu.com.  It seems to occur when you've inserted an Ubuntu CD and started the package manager.

  [Test Case]
  sudo apt-get remove synaptic
  /usr/lib/update-notifier/backend_helper.py add_cdrom test

  [Regression Potential]
  I think very low.  The only affected code path is right before this crashes unconditionally anyway.  So even if this screws something up, it can't make it worse.  We import a module from python-dbus, but we already were using python-dbus, so dependencies and module use aren't changing.
