The weave bug seems to be still present in scipy 0.7.1 

I am running Ubuntu 9.10 (Karmic)  and have scipy installed from source (since it is not in the repos) without problems, the required Atlas, ... libraries were installed using synaptic

ipython:
In [2]: scipy.__version__
Out[2]: '0.7.1'

Running a weave.blitz test routine:
"...
weave.inline(code, vars, type_converters = weave.converters.blitz)
..."

Output is:
starting weavefunc..
