warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object

Hello,

I am getting the following error:

warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object

The error appears 7 times 1 for each of the following lines in the file "sms_clickatell/sms_clickatell.module"
Ln: 195
Ln: 273
Ln: 278
Ln: 282
Ln: 286
Ln: 290
Ln: 294

I am sending out a blast sms, using clickatell 6.x-1.0 and sms framework 6.x-2.0-alpha1

If you have any ideas I would really appreciate it.
