Illegal use of string offsets causes E_ERROR instead of E_WARNING in PHP 5.
So the line 3300 in class.t3lib_div.php
unset($dataStruct['meta']) isn't compatible to PHP 5, because it's possible that there is only a String in $dataStruct.
A
if (isset($dataStruct['meta']) && is_array($dataStruct)) {
unset($dataStruct['meta']); // Meta data should not appear there.
}
solves the problem.

Is it sufficient to test for an array?

if (is_array($dataStruct)) {
unset($dataStruct['meta']);
}

Hi,
I've tested again and yes, it's sufficient to test for an array.

greets

Because of unsetting the 'meta'-Index it is not enough to check for the whole array. An isset-Condition on the 'meta'-Key should prevent from fatal error.

if (isset($dataStruct['meta'])) unset($dataStruct['meta']);

Another issue of this can read at bugreport 1869.

In the code in CVS there is a test earlier that checks is $dataStruct is an array. As in fact it is an error to call this function with an argument that is not an array.
