Problem

after upgrading to mw 1.17 various dpl calls generate the following warnings,

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/aiowiki/aiowiki/w/includes/parser/ParserOptions.php on line 274
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/aiowiki/aiowiki/w/includes/parser/ParserOptions.php on line 289

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/aiowiki/aiowiki/w/includes/parser/ParserOptions.php on line 317

this can cause when using the namespace parameter in a dpl call, also when using

Extension:DynamicPageList (DPL), version 3.2.1: Warning: No results.

the templates and calls haven't been changed from before the upgrade and were working perfectly in 1.16.5, also the dpl call still gives the correct results
