Bug Description
When wpa_supplicant is terminated normally (i.e. with SIGTERM or SIGINT or 'wpa_cli terminate'), it brings down any wireless interfaces it is managing. However, if wpa_supplicant is started by dbus activation and if the dbus messagebus is then shut down, it terminates abruptly and improperly without deconfiguring any network interfaces.
Note that wpa_supplicant has its PID file installed in /run/sendsigs.
This has been reported upstream (along with steps to reproduce and a patch) at:

This bug, along with bug 1124803 (in network-manager), means that when I connect my laptop to a wifi network, no attempt is made to disconnect from that network when shutting the system down. This in turn triggers a bug in my BIOS which causes this system to hardlock in the middle of BIOS post when I reboot while still connected to a wifi network:
