TYPO3 Core

Can you give me a hint, where this local variable $LANG appears?

I'm not sure what you mean. Nevertheless, I have uploaded my phpinfo output. The webserver runs on a virtualized ubuntu linux (hardy) from turnkey.

You can see the environment variable LANG on page 18 in the phpinfo file.

A clash with an environment variable? That's not possible to fix - $GLOBALS['LANG'] is used on many places and since ages.

I think, this issue was closed too soon.

I have had a look at the code and found the culprit:

instead of "if (!isset($GLOBALS['LANG']) ... " you should use "if (!is_object($GLOBALS['LANG']):

// Create an instance of language, if necessary.

- if (!isset($GLOBALS['LANG'])) {
if (!is_object($GLOBALS['LANG'])) {
$GLOBALS['LANG'] = t3lib_div::makeInstance('language');
$GLOBALS['LANG']->csConvObj = t3lib_div::makeInstance('t3lib_cs');
}

thanks for having a second look at this
kind regards

any feedback on this?

Okay, fine. I see no problem in using is_object().
