In an effort to help with this, I replicated the problem and now I'm locked out of rating any submission that's not an executable. Found no way so far to fix it other than hope everyone makes their submissions register as executables as opposed to the documents they actually are...which I did so I can confirm this is actually the case so please let me know if you now see Crawl in your rating queue...assuming you didn't get a chance to rate it before you stumbled into this problem.
