I have the same problem. When running the plot() function on my universe, it gives me `RuntimeError: OpenMC aborted unexpectedly`. If i run `openmc -p` from the same directory as my jupyter notebook, the following is written out

```auto
(openmc-env) <retracted> % openmc -p
                                %%%%%%%%%%%%%%%
                           %%%%%%%%%%%%%%%%%%%%%%%%

 =======================> PLOTTING SUMMARY <========================

Plot ID: 2
Plot file: plot_2.png
Universe depth: -1
Plot Type: Slice
Origin: 5 2 3
Width: 50 50
Coloring: Cells

Pixels: 400 400

 Processing plot 2: plot_2.png...
libpng warning: Application built with libpng-1.4.12 but running with 1.6.39
zsh: segmentation fault openmc -p

```

so the same error as for @madhofs. I installed OpenMC according to the normal procedure on the website, and I am using a conda environment.
