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)

Cheers,
Manuel
