Hello,
I have been using MPL 0.90.0 without trouble for some time. I do not use
any interactive backends and simply savefig to a pdf which my viewer updates
when the file is written to. This has worked very well for me until I just
tried to upgrade to MPL 0.90.1. I am running on G4 powerbook using fink for
python 2.5 and some other dependencies. The following code works fine
in MPL 0.90.0 and gives the error message below on MPL 0.90.1:
[code]
import matplotlib
matplotlib.use('PDF')
import numpy
import pylab as p
x = 2.*numpy.pi*numpy.arange(1000)/250.
y = numpy.sin(x)
plt = p.plot(x,y,'r')
p.savefig('test.pdf')
[/code]
[traceback]
