Hugin crashes on equi to Architectural projection

[Jan Martin]

Hugin 2011.1.0.13dd690b1ce1
Ubuntu 10.4

I am loading an equirectangular image of 6.5 MB. Set HVOF to 360 and projection to equirectangular.
When changing the projection to Architectural in Fast Panorama preview Huign disappears.

I am on Windows XP and tested it. I have something like that.
When setting the equirectangular projection to 360 degrees and change to architectural the picture disappears. Not Hugin.
When press fit under the projection tab of the fast preview it comes back with the real FOV

I got a spurious crash in a similar situation, switching between Architectural and Equirectangular forth and back.

The crash is not reproducible with 2018.0.
I committed a further fix with improves the calculation of vfov.
