[SheriffHosni]

Calendar not showing when I click on show calendar from indicator menu and it remains dimmed (unclickable).

menu shows the coming events once the calendar starts, and all menu elements are clickable,
but when i click show calendar nothing happens, and all menu elements are dimmed then,
only events, help and exit are clickable, but add new calendar, add new event, sunc with google calendar, show calendar and preferences all are dimmed.

Me pasa tambien a mi (Elementary OS Luna 64bits)
Sin embargo, si lanzo calendar-indicator desde consola funciona perfectamente
Un saludo
