Bug summary
ax.xaxis.set_major_locator will let matplotlib throw a font not found error. But if we remove ax.xaxis.set_major_locator, the error disappears.
Code for reproduction
from matplotlib import ticker
import matplotlib.pyplot as plt
plt.rcParams['text.usetex'] = True
plt.rcParams['font.family'] = 'serif'
plt.rcParams['font.serif'] = 'Times'
fig, ax = plt.subplots()
ax.plot([1, 2, 3])
#!!!!! If we comment out the following line, the code will run without error
ax.xaxis.set_major_locator(ticker.LinearLocator(numticks=5))
fig.savefig('test.pdf')Actual outcome
Throws error:
