I am not sure this is a version error or some other bug somewhere 
presumably on the client side.  I had this problem my self at some point 
a week or so ago. I had noticed that my client suddenly churned through 
tiles far too fast and when I checked those on the server they were 
indeed all completely blank where they shouldn't have been. A simple 
restart of the client fixed it and since then I hope I haven't uploaded 
any more broken tiles, but it looks like other people apart from beldin 
are affected by this problem too.

In addition, there seems to be another problem with blank tiles. For 
example around the Boston area, there are large areas of blank tiles. 
These are all uploaded by "Nonexistent User ID 0". I suspect this is a 
different problem, as it looks too widespread to be cause by an 
individual uploader.
