This could be a problem with my own installation, though. Maybe worth to look into it.

Thanks for the report! This seems to be related to a fig.savefig() call, which is quite strange. Can you confirm if a MWE like this works in your installation?

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 5, 50)
y = np.sin(x)
fig, ax = plt.subplots()
ax.plot(x, y)
fig.savefig('tmp.png')
