>> Type: bug
>> 
>> Branches: trunk, 4.2
>> 
>> BT reference: http://bugs.typo3.org/view.php?id=9511
>> 
>> Problem:
>> getHtmlTemplate() in typo3/template.php calls getURL in the following
>> way: t3lib_div::getURL($this->backPath . $filename)
>> 
>> For tt_news $this->backPath . $filename =
>> "../../../../typo3/../typo3conf/ext/tt_news/mod1/mod_ttneypo3conf/ext/tt_news/mod1/mod_ttnews_admin.html"
>> which can't be opened on some linux servers because of typo3/../
>> 
>> Solution:
>> resolveBackPath() removes "typo3/../" which works.
