There's actually a real MPL bug in there (not just the
NotImplementedError) but I'll report it separately in a minute.

Well, unfortunately it seems that inkscape is crashing python
itself... I made a trivial .eps in mpl with:
In [1]: plot(range(10))
Out[1]: [<matplotlib.lines.Line2D instance at 0x8f45a8c>]
In [2]: title(r'Some \LaTeX $\int_0^\infty f(\gamma) d\gamma = 1$')
Out[2]: <matplotlib.text.Text instance at 0x8f4590c>
In [3]: savefig('foo.eps')
and when I tried to load it into inkscape, I got this very nasty traceback:
*** glibc detected *** /usr/bin/python: free(): invalid pointer: 0x4081e4e0 ***
======= Backtrace: =========
/lib/tls/i686/cmov/libc.so.6[0x400ee7cd]
/lib/tls/i686/cmov/libc.so.6(cfree+0x90)[0x400f1e30]
/usr/lib/skencil/Sketch/../Lib/streamfilter.so[0x404e7ce5]
/usr/lib/skencil/Sketch/../Lib/streamfilter.so[0x404e7cd2]
/usr/bin/python[0x8110e6a]
/usr/bin/python(PyEval_EvalCodeEx+0x313)[0x80c9903]
etc.
At this point, this is really becoming OT for the mpl list, so I'll
stop. But if anyone has the time, it might be worth sending this
example to the inkscape list so they work on it and hopefully fix it.
Cheers,
