I don't know what else to tell you. It's something wrong with your  
PHP/Apache. PHP 5.3.3 is 3 years old. There were hundreds of bugs  
fixed since then, and at least a dozen stream related fixes.

My guess is that it's a bug in PHP's stream filter handling but that's  
just an educated guess.  If you would rather poke around the code than  
update PHP, you can look in  
Horde_ActiveSync_Message_AirSyncBaseFileAttachment::_checkEncoding()  
or Horde_ActiveSync_Wbxml_Encoder::_outTermStr()

The former adds a stream filter to encode the data to base64 as  
required by the spec. The later is where the stream is ouput 8192  
bytes at a time.

If you insist on not upgrading your 3 year old PHP you can read out  
the stream into a string, convert it to base64 and return it from the  
first method (though this will absolutely kill performance as the  
entire attachment will be kept in memory, along with the larger base64  
encoded version of it).
