Comment 4 for bug 785803

This is a bug I've seen lots of times, but this is without the --no-optimize parameter.

I usually find that it goes away if I rearrange the order of photos in the project, or rotate the scene slightly to give the blending a different geometry.

Can you upload the .pto project as a test case? Since it shows the bug without seam optimisation it might be useful tracking it down.
