TYPO3 Core

This is no bug. See TSref, config.stat_titleLen: "The length of the page names in the path written to logfile/database". It defaults to 20. Set it to something higher (maximum is 100).

Lines 1607-1608 in class.t3lib_fe.php do the processing:
$len = t3lib_div::intInRange($this->config['config']['stat_titleLen'],1,100,20);
$pageName = str_replace('[path]', ereg_replace('[^\.[:alnum:]\/_-]','_',$this->sys_page->getPathFromRootline($temp,$len)).'/' ,$pageName);

Fine with me, so let's close this one.
