Note that the error message and the button "Details" are provided automatically by the Akonadi library if Akonadi fails to start up. AFAIK, you would see exactly the same display in any other Akonadi-dependent application if Akonadi failed to start. So, although you see the fault in KAlarm, the bug actually lies in the relevant Akonadi library package.
