what's that "calendar storage" warning message?

[jess]

My A13-Olinuxino-WiFi android board occasionally comes with "Unfortunately, calendar storage has stopped".
Any clue what that is and how to disable it?

Potentially a calendar crash.  Disable google account syncing and cleanup the data for the calendar. It might help.

Oh yeah, the google account sync - I can see the reason
