Description
Bug summary
When I set rcParams['text.usetex'] = True, I can't skip line in date format.
For example, I can't use DateFormatter('%d/%m\n%Y').
Removing the skip line \n it works: '%d/%m\n%Y' --> '%d/%m/%Y'.
It was working before. It's stopped working since my last update/upgrade of Anaconda.
Code for reproduction
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.dates as dates
mpl.rcParams['axes.labelsize'] = 15
mpl.rcParams['figure.figsize'] = [12, 3]
mpl.rcParams['text.usetex'] = True
# mpl.rcParams['text.usetex'] = False
FMT = dates.DateFormatter('%d/%m\n%Y')
# FMT = dates.DateFormatter('%d/%m/%Y')
plt.axes().xaxis.set_major_formatter( FMT )
plt.show()Actual outcome

Expected outcome
If I set rcParams['text.usetex'] = True, I have to change the data format:
Additional information
Has this worked in earlier versions?
Yes.
Do you know why this bug is happening?
I couldn't find the LOG file cited in the Actual outcome (pasted above, the last line).
I mean, I couldn't find this file: Transcript written on 09efec18b9a3c1b4d23927d49f15f25f.log.
However I managed to find a TEX file with the same name into '/home/.cache/matplotlib/tex.cache/'
The contents of this TEX file are (I think it may help):
