ksort() error in global.php

[Nullifi3d]

[02-Feb-2006 22:18:56] PHP Warning: ksort() expects parameter 1 to be array, null given in /home/*****/public_html/dev/global.php(349) : eval()'d code on line 28

I don't see anything wrong with my global_start plugin. I even tried disabling it and emptying it, but the error still occurs on every page load. It doesn't print to the screen, but instead writes to the error_log file on every page load.
