PyPlot: KeyError: key :colormaps not found

I have a fresh install of 1.10.4 using juliaup on Linux openSUSE 15.5. S I load only PyCall and PyPlot into the registry. The command using PyCall, PyPlot results in:

ERROR: InitError: KeyError: key :colormaps not found

during initialization of module PyPlot

However, from here I am able to plot simple plots so while julia reports an error, I have yet to have a plot fail. Running python3 and importing matplotlib and matplotlibl.colors works ok. I have also tried to rebuild PyCall and PyPlot but the "error" persists.

Should be fixed by #592

After Pkg up PyPlot refreshed and now the error is gone. Thanks.
