For the record, the machine panic’ed. The vagrant development virtual machine went down with:

but the panic only happened when I tried to vagrant up development. I suspect something wen wrong on the underlying host because there was:

In /var/log/syslog. Before that syslog is clean from 07:00 to 14:40. I hard rebooted from the horizon panel.
The SecureDrop demo category was created in the forum and linked from the demo page so it is easier for people who run into a problem to report it or just discuss the demo in general.
