While having apport collection info about upower, it made the kernel crash with nullpointer deref in kernel proc khidpd. Reboot failed, kernel was semi-hung afterwords. I suspect the crash might be triggered by reading/probing stuff about bluetooth or whatever. I have no time at the moment to report this as a separate bug, sorry. Traces appended below.
