Phil,

You didn't mention whether this was "incidental" silkscreen like a 
"ElementLine" that overlapped the pad or something related to the pad 
itself..  A previous version of pcb would in some cases generate 
silkscreen rectangles in the gerber output on some surface mount pads.  
I was never able to figure out what combination(s) of features would 
cause this to happen, but it does appear to be fixed in the most recent 
revision of pcb.  (You can and should look pretty carefully at your 
gerber output to make sure it is correct.)
