According to instructions in class.gzip_encode.php there must be another call, which is neither made, nor possible with BE architecture (it is not a problem in FE). Therefore compression never works. class.gzip_encode.php requires either a call to its constructor after output is completed (not possible with Backend modules) or "autoappend" PHP file, which is not possible either.

Notice that we cannot use ini_set('zlib.output_compression'), it simply does not work from withing a file (but works from .htaccess). So I decided on ob_gzhandler(), which is old good proven working function. Additionally this bugfix will automatically fix http://bugs.typo3.org/view.php?id=3071 (positive side effect).

no objection, but in the other thread in BT (#3071) you mentioned that 
this will solve the problem. Can you explain how this is related to 
empty lines in php-files?
