I managed to re-create the error, although today it took me a few tries. I
realized that perhaps I'm the cause of the problem. Specifically, the error
occurs after the following steps:
1) In "Software Sources", enable a new source (e.g. ppa.launchpad development
package), close, and reload.
2) Launch update manager (either manually or automatically) ---> new updates
appear
3) Launch "Software Sources" again while update manager is open, but before
installing the updates, disable the same source, close and reload
4) Error pops up.
Here is the CLI output:
:~$ apt-config dump | grep Update
APT::Periodic::Update-Package-Lists "1";
APT::Update "";
APT::Update::Post-Invoke-Success "";
APT::Update::Post-Invoke-Success:::: "touch
/var/lib/apt/periodic/update-success-stamp 2>/dev/null || true";
APT::Update::Post-Invoke-Success:: "/usr/bin/dbus-send --system

:~$ dpkg -l | grep packagekit

If the error occurs again in a different situation, I will be sure to note why.
