title: Blank arguments in Drupal view not working
body: <p>I'm stuck on (what I think is) a simple views issue.</p>
  
  <p>I have a view with a page display, with a path of:
  /mydir/%/%</p>
  
  <p>Some URLs I would hit are:
  /mydir/pc/2008/
  /mydir/xbox/2007/
  /mydir/pc/</p>
  
  <p>%1 and %2 are different CCK fields. When I specify the path with both arguments:
  /mydir/pc/2008/
  it works great. But the one argument paths:
  /mydir/pc/
  /mydir/xbox
  aren't working at all. I get a 404 page not found (and I did not select the 404 option in my view).</p>
  
  <p>The breadcrumb links on this page:
  /mydir/pc/2008/
  link to 
  /mydir/pc/*
  which just outputs a * to the screen. Sometimes I've been able to configure it to output all the right stuff with
  /mydir/pc/*
  but I don't want the * there, I just want
  /mydir/pc/</p>
  
  <p>I tweaked all of the argument settings for each argument in every way possible I can imagine, and I can't get my desired behavior, which is that this URL:
  /mydir/pc/
  just ignores or uses any match for the second argument and matches the first.</p>
  
  <p>Also odd: The preview tool in the view works correctly, if I pass in just pc/ in the arguments box. The URL that is outputted in the views preview ouput is also correct: /mydir/pc/. But if I click on that (after saving), I still get the 404.</p>
  
  <p>What am I doing wrong?</p>
