Re: [Matplotlib-users] Segmentation fault with EPS output on matplotlib =0.98.5.2
I'm using 'xpdf' now, I think it must be ghostscript acting up. I only need
eps output infrequently so I'll stick with this workaround for the moment.

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.
