Comment 54 for bug 751175

Earlier this week a dbus patch came through. After rebooting I thought the behavior with indicator-datetime-preferences had disappeared. However after some reboots the problems still exists. First time launch causes a hang in de application. Killing it manually the application does work.

Dbus-monitor still gives this in its results (along other things):
