The URL http://www.pixelbeat.org/pixelbeat.asc is a valid URL, but it results in
a "302 Moved Temporarily" redirect, which rpm doesn't seem to like.

The same operation on FC3 (rpm-4.3.2-21) doesn't work either, but results in
less noisy error:
error: http://www.pixelbeat.org/pixelbeat.asc: import read failed.
