When you say you are denied, exactly what happens? I've run into times when I've logged in and I get the unaltered front page again. Logging in again usually works. There is something strange going on. Logging in on projects.scipy.org/scipy/numpy usually redirects you to scipy.org/scipy/numpy, at which point you need to log in again. I tried it several times now - register - login - it doesn't accept the password. Then it redirects to scipy.org/scipy/numpy as you said. Then I went back to the original page and then the login worked. (But I did the same trick before and it didn't work). Anyway, it seems to be working now, thanks for the help.

[Numpy-discussion] numpy 1:1.0.4: numpy.average() returns the wrong result with weights
Hi, more details in this bug report. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=467095 The bug report offers a fix for this problem. It seems to me this is not fixed even in the latest svn.

It appears to be fixed in SVN (that was quick!). But the Debian bug report also points out a peculiar unnecessary use of eval; the code is also slower and uses more memory than it has to. Attached is a patch to cure that.
