I don't want to see that Discard/Keep dialog when downloading a pdf file in browser. I just want it to automatically save to my default location. I'm using chrome on Ubuntu 13.04.

I fear that the only way to disable this is to patch Chrome.

The file that contains the blacklist is /src/chrome/browser/download/download_extensions.cc.

One would just need to remove the line containing { "pdf", AllowOnUserGesture }, and recompile.

Or replace DownloadDangerLevel GetFileDangerLevel(const base::FilePath& path) with:

DownloadDangerLevel GetFileDangerLevel(const base::FilePath& path) {
  return NotDangerous;

which seems to have some irony to it.

UPDATE: I wrote a patch and have successfully tested it.

If on Gentoo, you can just place this in a file in /etc/portage/patches/www-client/chromium/ and emerge chromium.
