I think there should be some kind of error message somewhere (or is 
there any log I have not considered). What wonders me, is that it worked 
in Typo3 4.1.5. Perhaps by adding to the cache (after it stopped adding 
content) some sort of Error message. "Stopped writing to cache because 
of an invalid character" or something.
