I see this too (since r8541) on 64 bit Ubuntu. I see that the change has also gone into the 1.4.x and 1.5.x branches (r8542 & r8543), I guess that those commits should be reverted until trunk is fixed.
I cannot install the most recent svn version of scipy
Scipy doesn't build because numpy can't be imported.. Cheers, Scott
