With Python 2.5, pyvorbis 1.4 crashes, as does the pyvorbis 1.3 in extra.

A patch that was created for this was in this ubuntu bug:
https://launchpad.net/ubuntu/+source/pyvorbis/+bug/81243
Patch is here:
https://launchpad.net/ubuntu/+source/pyvorbis/1.3-1.2ubuntu2

I modified the patch to work for both pyvorbis 1.3 and the pyvorbis 1.4 in testing.
The two patches are attached.

A crash test is below. Opening two files and reading some data from them insures
that there will be a crash with the unpatched pyvorbis.

File: pyvorbistest.py

#!/usr/bin/python
import ogg.vorbis
vf = ogg.vorbis.VorbisFile('test.ogg')
print vf.bitrate(0)
vf2 = ogg.vorbis.VorbisFile('test.ogg')
print vf2.bitrate(0)


Below is a crash example:
