Segmentation Fault when Plotting Area

[toomanycats]

Ubuntu 20.04

When I try to plot an area I get a seg fault. I've not been successful in getting the core dump to actually show up.

I have nailed down in the source where this happens: voaAreaPlot.py

            ax.set_extent([area_rect.get_sw_lon(),
                    area_rect.get_ne_lon(),
                    area_rect.get_sw_lat(),
                    area_rect.get_ne_lat()], projection)

The seg fault does not occur if i comment out the projection. I suspect something is wrong with my GEOS installation.

cat Version.txt

# GEOS Versions

GEOS_VERSION_MINOR=11
GEOS_VERSION_PATCH=0

# OPTIONS: "", "dev", "rc1" etc.

# GEOS CAPI Versions
#
# - For a release with no interface changes just bump REVISION.
#   ( Even if *nothing* changed in CAPI )
# - Adding interfaces, bump CURRENT/AGE, set REVISION to 0.
# - Deleting interfaces / compatibility issues - bump CURRENT, others to zero
#   ( THIS MUST BE CAREFULLY AVOIDED )

I don't understand why this works, but it did:
