Which parameter did you try to optimize?
Could you provide the project file and maybe the images. Otherwise it is
difficult to find the bug.

Title:
Singular matrix in vig_optimize
Status in Hugin - Panorama Tools GUI:
Incomplete
Bug description:
I noticed a project was causing Hugin to hang when doing a photometric
optimization. I tried running vig_optimize on the command line to
see what was happening and got:
$ ./vig_optimize -v -o /tmp/xx.pto '/Users/bst/Desktop/TMP
Export/4452-HDRPano LR/_MG_4452-_MG_4556.pto'
