I've heard of it happening a lot with Campy NR and similar cranks -- seems like it was common BITD to use a file to round over the corners of the web to prevent cracking.
I don't have much personal experience to bring to the table either way -- I started riding road bikes in 2009, and my equipment is late-80s and newer. I may never find out if the preventative filing I've done to my cranks helps or hurts.
