[TYPO3-core] strcmp expects parameter 2 to be string

[Stefan Frömken]

In extension manager->language settings I get following error when I 
choose a language and click on save:

Warning: strcmp() expects parameter 2 to be string, array given in 
C:\xampp_webserver\htdocs\t3lib\class.t3lib_befunc.php on line 2909

I found this row:

if (is_array($CHANGED_SETTINGS) && isset($CHANGED_SETTINGS[$key]) && 
strcmp($settings[$key], $CHANGED_SETTINGS[$key])) {

and changed it with

if (is_array($CHANGED_SETTINGS) && isset($CHANGED_SETTINGS[$key]) && 
strcmp($settings[$key], (string)$CHANGED_SETTINGS[$key])) {

now it works.
