[wp-testers] Upload Media Broken

[Ben Huson]

In the recent updated version 2.7-beta3-9909, the Flash media uploader
is now broken for me.
(only tested in Safari - was working fine on yesterdays update)

Select a file to upload and nothing appears to happen, no progress bar etc.

If you then click on the gallery tab you find that the file has
actually uploaded OK, there was just no progress or success indicator.
