Here is what happens: when the prerm script is started, /usr/bin/python
symlink points to /usr/bin/python2.7, but the latter has not yet been
unpacked. So the python script update-python-modules cannot be run… Said
otherwise, python-minimal 2.7.3-4 has been unpacked, but
python2.7-minimal has not yet been.

It is clear that this is not a python-numpy bug, but at this stage I
don’t know which package to reassign it to (python-defaults,
python-support, or even apt ?).
