Looking at my logs I see repeated instances of this:
May 16 14:58:14 server apache2: PHP Warning: in_array() href='function.in-array'>function.in-array</a>: Wrong datatype for second argument in /var/www/secure.ideasynthesis.com/analytics/core/Tracker/Action.php on line 156
I'm uncertain what the best way of providing additional information on this is. I'm running 0.6.1.
What version of php?
As it appears to be in the same section of code as #1347, I'm going to mark this as a dupe.
