dbus 'connection' should not be NULL

I installed goodvibes from the AUR on Arch. It worked fine for a while but recently stopped opening. When I try to run it from the terminal, I get this error before the crash:

$ goodvibes
**
ERROR:../goodvibes-v0.7.4/src/feat/gv-dbus-server.c:641:gv_dbus_server_enable: 'connection' should not be NULL
Bail out! ERROR:../goodvibes-v0.7.4/src/feat/gv-dbus-server.c:641:gv_dbus_server_enable: 'connection' should not be NULL
Aborted (core dumped)

dbus.service appears to be running fine. Is anyone else seeing this? I got it on a fresh install.
