[TYPO3] TYPO3 4.2.0 and pi_linkT (t3lib_div::implodeArrayForUrl)

[Alessandro Tuveri]

Hi Folks
I don't know why but sometimes using TYPO3 v4.2.0 occurs an error like this:
PHP Catchable fatal error: Arugment 2 passed to  
telib_div::implodeArrayForUrl() (etc....)

I investigated and discovered that within:
typo3/sysext/cms/tslib/class.tslib_pibase.php
on line 307

this is the listing:

function pi_linkTP($str,$urlParameters=array(),$cache=0,$altPageId=0)   {
                 $conf=array();
                 $conf['useCacheHash'] = $this->pi_USER_INT_obj ? 0 : $cache;
                 $conf['no_cache'] = $this->pi_USER_INT_obj ? 0 : !$cache;
                 $conf['parameter'] = $altPageId ? $altPageId :  
($this->pi_tmpPageId ? $this->pi_tmpPageId : $GLOBALS['TSFE']->id);
                 $conf['additionalParams'] =  
$this->conf['parent.']['addParams'].t3lib_div::implodeArrayForUrl('',$urlParameters,'',1).$this->pi_moreParams;

there is a call to:
t3lib_div::implodeArrayForUrl(...)

where adding this few lines (before the call above):

                 if($urlParameters == NULL) {
                         $urlParameters = Array();
                 }

you can solve the problems. I don't know if TYPO3 was modified or if  
PHP 5.2.x can't understand that the parameter passed as:
NULL

is misinterpreted as a normal variable.

Any comments or ideas?!?
Thank you
