I've seen this problem before. My money is on a corrupted file.
Does it happen every time? What happens when you try to copy the file someplace else using the Finder?
Also, you might try repairing the volume using Disk Utilities. If this is your startup volume, you'll need to run the Disk Utilities while booted from another partition or your installer DVD. (It's also possible to repair it at startup with a little command-line magic.)
