I noticed the following error when in my application I try to export the
plot in EPS format. The odd thing is that the export actually works and
produces a good eps file, but nevertheless...

please submit a short script that reproduces the problem.
I have just reproduced it by doing an histogram in an interactive
ipython --pylab session and then exporting as 'figure.eps'.
Just:
a=[...] <--numbers to histogram
hist(a)
savefig('hist001.eps')
gives:
exceptions.OSError Traceback (most
