[SciPy-user] problem with scipy.stats.distributions ?

[PGM]

Hello,
I recently update to numpy 1.0b5 and scipy 0.5.1, and I'm running into this 
message:
#....................................................................
>>> scipy.stats.distributions.norm.ppf(0.95)
---------------------------------------------------------------------------
/usr/lib64/python2.4/site-packages/scipy/stats/distributions.py in ppf(self, 
q, *args, **kwds)
    551         place(output,cond2,self.b*scale + loc)
    552         goodargs = argsreduce(cond, *((q,)+args+(scale,loc)))
--> 553         scale, loc, goodargs = goodargs[-2], goodargs[-1], 
goodargs[:-2]
    554         place(output,cond,self._ppf(*goodargs)*scale + loc)
    555         return output

/usr/lib64/python2.4/site-packages/numpy/lib/function_base.py in insert(arr, 
obj, values, axis)
   1165         if (obj < 0): obj += N
   1166         if (obj < 0 or obj >=N):
-> 1167             raise ValueError, "index (%d) out of range (0<=index<=%d) 
"\
   1168                   "in dimension %d" % (obj, N, axis)
   1169         newshape[axis] += 1;

ValueError: index (1) out of range (0<=index<=1) in dimension 0

Would anybody have any idea of what it means ?
Thx in advance
