Safari now claims to accept (shows the cursor with the green + orb) and seems to try to load anything dragged into it - things like application bundles, folders or zip files. The title is blanked and history functionality for that tab/window is dead.

Okay, the problem is that the drag and drop code had an "improvement" that short circuited the evaluation of _web_best_URL if the dragging Pasteboard contained any url. _web_best_URL filters out insane URLs (eg. directories) so this was bad. This fix stops directories from being accepted.
All other files are accepted, and will bring up the finder if the dropped file isn't viewable with webkit.

+ Drag a file that WebKit doesn't recognise -- eg. a disk image, tarball, etc.<p>
Would be better to either wrap this in a <p></p> pair, or use <br>
