I cannot reproduce this error.
And I'm not sure if this is a bug in matplotlib or ghostscript.
You may try to use different distiller.
pl.rc('ps', usedistiller="xpdf")
In my machine, both ghostscript and xpdf option works fine.
But my gs version is different than yours
GPL Ghostscript 8.61 (2007-11-21)
If the xpdf option woks, I think it is more likely that this is a bug in gs.
