Bug#1002923: python3-matplotlib: Plotting with usetex results in 'Script file /usr/share/matplotlib/mpl-data/kpsewhich.lua not found'

[Kumar Appaiah]

Package: python3-matplotlib
Version: 3.5.0-5
Severity: normal

Dear Maintainer,

I tried running this code:

import pylab

pylab.rc('text', usetex=True)
pylab.plot([1, 2, 3], [1, 4, 9])
pylab.show()

This results in the following error:

Exception in Tkinter callback
