Caminfo uselabel option fails under isis5.0.0-RC1

[lwellerastro]

ISIS version(s) affected: isis5.0.0-RC1

Description
caminfo will fail when uselabel=true to write out polygon information. It works if polygon=true and the associated parameters are specified.

uselabel=true works for the same images under isis4.4.0.

How to reproduce
See data under /work/users/lweller/Isis3Tests/Caminfo/5.0.0-RC1/. This image was processed entirely under isis5.0.0-RC1 (see proc.scr for details)

Fails:
caminfo from=TC1W2B0_01_01899S769E1325.lev1.cub to=TC1W2B0_01_01899S769E1325.lev1.pvl isislabel=true geometry=true originallabel=true statistics=true camstats=true linc=100 sinc=100 uselabel=true

Works:
caminfo from=TC1W2B0_01_01899S769E1325.lev1.cub to=TC1W2B0_01_01899S769E1325.lev1.CALCPOLY.pvl isislabel=true geometry=true originallabel=true statistics=true camstats=true linc=100 sinc=100 polygon=true inctype=vertices numvertices=40

Possible Solution

Additional context
I also ran this against one of the LROC NAC findfeatures images from another post (originally processed under isis4.4.0) to be sure it wasn't a Kaguya TC problem and it fails as well when uselabel=true but works if I use polygon=true.

All images involved have had footrprintinit run on them prior to caminfo.
Qmos recognizes and draws the stored polygon information.
