Additional notes: This bug has persisted, so it's probably not due to the server. I have no problem saving a .../lecture/ page from the browser to an HTML file, so I don't understand why the script downloads gibberish. index.html gets similarly corrupted (about as often)

Thanks Dan. Unfortunately I do not have the time to really follow up on this, any help welcome. The way a browser interacts with a page is quite different that requests does. coursera-dl used to be based around the mechanize lib and that seemed more stable in this respect. You can try the mechanize branch on github (It should still work I believe) and see if that helps.
