I can't seem to reproduce this on a 32-bit RHEL4 machine with:
python-2.5.4
matplotlib-0.99.1.2
GNU ghostscript 7.07
and viewed with any of:
Adobe Reader 8.1.7
xpdf 3.00
ggv 2.8.0
(sorry no evince on RHEL4)
What versions of these tools are you running? Do you have any
customizations in your matplotlibrc file? Can you send me (off-list)
the ps/eps and pdf files in question?
