there was no recent update to light-locker. What did change on your system?
Unlock works fine here so I'll need more information in order to reproduce.

I guess I don't normally run it from the command line.

dbus[27173]: arguments to dbus_message_new_method_call() were incorrect, assertion 
"path != NULL" failed in file ../../../dbus/dbus-message.c line 1362.
This is normally a bug in some application using the D-Bus library.

  D-Bus not built with -rdynamic so unable to print a backtrace
