Really? Note that Matthias had text.usetex=False.
I tried various configurations:
text.usetex=True
xlabel( "$[$") okay
xlabel(r"$\[$") okay
xlabel( "$\[$") no error, but also no label displayed
text.usetex=False
xlabel("$[$") failed with
Expected end of text (at char 0), (line:1, col:1)
xlabel(r"$\[$")
xlabel( "$\[$") no error, but displays a star symbol
In the last two cases I got a warning
mathtext.py:722: MathTextWarning: Unrecognized symbol '\['. Substituting
with a dummy symbol.
% sym.encode('ascii', 'backslashreplace'), MathTextWarning)
