geoviews (via pip) causes kernel crash in jupyter

See original GitHub issue

Polygon objects cause geoviews to crash without any error. Have yet to narrow down what is actually causing this - but it seems to be something in geoviews as cartopy, shapely, geopandas works fine with the same shapefiles. All installed via pip.

Examples from the geoviews documentation cause the same crash:

import geoviews as gv
import geoviews.feature as gf
import xarray as xr
from cartopy import crs

gv.extension('bokeh', 'matplotlib')

(gf.ocean + gf.land + gf.ocean * gf.land * gf.coastline * gf.borders).options(
    'Feature', projection=crs.Geostationary(), global_extent=True, height=325
).cols(3)

In my particular use case geoviews crashes only when working with gv.Polygons. Other layers such as datashader (RGB) and map_tiles work as expected.

No error is given but the kernel crashes when the plot object is called - tested in both jupyter lab and notebook.

Same thing happens in a fresh virtualenv. Not sure how else to diagnose as no traceback is returned, nothing in the jupyter console apart from:

[I 15:53:08.237 NotebookApp] KernelRestarter: restarting kernel (1/5), keep random ports
