Thanks for reporting this bug and helping to make Ubuntu better. This crash appears to be caused by a configuration error: org.gnome.Evolution.DefaultSources is provided by evolution-data-server- common, which is required by evolution-data-server, which is required by indicator-datetime. So if the install is correct, DefaultSources should be available for indicator-datetime.
The first thing I'd try is confirming that both of those packages are installed, and reinstalling them as necessary. ** Changed in: indicator-datetime (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-datetime in Ubuntu.
