The log shows that for some reason it is pulling in
BitstreamVeraSerif-Roman instead of Arev Sans for that character. It
could be that it isn't finding the Arev fonts on your system.
Can you send your matplotlibrc file? (Particularly the mathtext.*
options...) Also, can you set "verbose.level" to "debug-annoying" and
send us the output?
Cheers,
Mike
