[ptx] optimization problem

[Emmanuel]

Hi,

I have some problem when doing optimization. It does find 0 for the distance 
of all control points...
see snapshot (in french):

Nevertheless, it clearly does some optimizing (I can make bad but 
"reasonnable" stitching).

I'm using version rc1 and libpano 2.0.9 (it is the mandriva plf package 
libpano12_0-2.7.0.9-1plf).

What can be the origine of this problem ? Is it related to panorama tools?
