Summary: Delay when calculating Field of View

Initial Comment:
Hello,

With version 0.5rc1 under linux ubuntu latest unstable,
amd64 arch.
Whenever I click on 'Calculate Field of View', the
program hangs and sits there waiting with 100%CPU for
about a minute. This is only on my amd64 machine, which
should be really fast (3GHz proc and 1Gram). When I ask
gdb what hugin is doing, I always end up having this:

#0  0x00002aaaad5edadf in __signbitl () from /lib/libm.so.6
#1  0x00002aaaad5eeba2 in __signbitl () from /lib/libm.so.6
#2  0x00002aaaad5ee9f7 in __signbitl () from /lib/libm.so.6
#3  0x00002aaaad5cb7c0 in tan () from /lib/libm.so.6
#4  0x00002aaaacdccc96 in rect_sphere_tp

doCrop=false, 
    cropRect=@0x7fffffffab20, circularCrop=false,
transf=@0x7fffffffbac0, 
    imgRect=@0x7fffffffc9c0, alpha=@0x7fffffffab00,

PT::estimateImageRect<PTools::Transform>

...

Do you think it is a bug in __signbitl ? Or do you have
any clue where I should look for more info ?
Thanks a lot.
