I have the exact same problem. Fortunately the website itself still works.

Let me join the unhappy club: got the same fatal error after updating the plugin!
Any solutions yet?
Same problem. First time I try to login, I get:
Warning: array_search() expects parameter 2 to be array, object given in /home/r25/public_html/wp-content/plugins/all-in-one-event-calendar/all-in-one-event-calendar.php on line 160
Fatal error: Cannot use object of type stdClass as array in /home/r25/public_html/wp-content/plugins/all-in-one-event-calendar/all-in-one-event-calendar.php on line 160
But if I hit the back button on the browser and try again, it works. Still, a pain in the butt…
It seems as though everything works fine except for two things:
1. I no longer have my stats on my dashboard &
2. I get the error message when I try to access my plugins.
Also getting these warnings continually, several per minute, in an error log:
[06-Mar-2014 02:03:54 UTC] PHP Warning: array_combine() [function.array-combine]: Both parameters should have at least 1 element in /home/r25/public_html/wp-content/plugins/all-in-one-event-calendar/app/model/class-ai1ec-settings.php on line 902
