[TYPO3-english] ImageMagick 6.8.0-10 2012-12-16 Q16 + TYPO3 V6.X too dark images

[BVB Media (Bas van Beek)]

Is anybody aware of the fact that using the bleeding edge version of ImageMagick 6.8.0-10 (build date: 2012-12-16) with TYPO3 V6.X results generates too dark images?
 
I've found some tips on Google about changing the parameters in t3lib/config_default.php, but that didn't really help.
 
Does somebody have a specific solution for this problem?
