I do not have any good explanation (bad memory?). When checking the
copytest003.capture.bz2 file in the http server storage directory
I get the same results as you. However I also have the original file
stored still and comparing them with cmp -l gives
 20558656 124 104
so obviously a bit has been flipped. I have now replaced the
erroneous file with a good copy, so you should be able to download again.

Btw, I got a "traditional" hang now on my first attempt to copy
copytest003.capture.bz2 from old_pc to new_pc just using scp.
