I am having this exact same problem regardless of dataset.  
I've been using affyQCReport for years and 
this is the first time I'm come across it.  
Could it be related to the mac platform?  
This is the first time 
I've tried to run using 64-bit mac version of R.  
The linux 64-bit version of R generates the qc plots fine.
