[ptx] Bug in Hugin for many images

[mathieu.tobie.ptx at voila.fr]

 Hi!

I am new in this forum...

I tried Hugin (0.4 pre) to stitch many photos taken by my drone (about 50 photos). I want to generate automatically keypoints so I use autopano-sift 1.4 created by sebastian nozowin : http://user.cs.tu-berlin.de/~nowozin/autopano-sift/

Sometimes, using the option "Rectilinear", it works well and sometimes not...

The facts are the following :
For the same project .pto:
1- Using autopano, I generate keypoints for 16 images (for example) : when I launch stitch in "Rectilinear", it bugs, in "Equirectangular", it works.
2- I remove photo by photo to see if one creates the bug : I see if there are 12 photos, it works in "Rectilinear" and "Equirectangular".
3- I take the 13th photo with the 12th: it bugs in "Rectilinear", but not in "Equirectangular" !
4- I create a new project with the 12th and 13th : I put keypoints manually (without autopano) : it works for the 2 options.
5- So I think it is due to autopano, but when I just create automatically with autopano a ".pto" with the 12th and 13th, it works for the 2 options!!!

So to sum up, it always works in "Equirectangular", but I can't determine why "Rectilinear" bugs when there are many images (and coming from autopano)!

I have the following messages:

I could always use Equirectangular but it doesn't give me the results I want cause it is far too deformed !
So i'd like to stay in "Rectilinear"...

Here are joined my 3 projects pto (I can't join photos because they are too big)...

1-  test_12_and_13_coming_autopano : there were 16 images : keypoints and pto generated by autopano and then I removed all images except 12th and 13th, then saved with Hugin.

2- created_manually.pto : same images butr keypoints created manually

3 - with_autopano : same images but keypoints and pto created by autopano.
The last two pto work...

(I hope it is not too big in memory).

Regards,
Mathieu Tobie.
