xerces-c-vc9 contians a funny tar file that core python libs can not decompress

[jpalmer]

The xerces-c-vc9-3.1.1-3-devel.tar.bz2 tar file in the x86\release\xerces-c folder seems to be compressed in a way that stops python from decompressing it. All other files on the site are fine but this one returns the following error:

import bz2
import tarfile

file ='xerces-c-vc9-3.1.1-3-devel.tar.bz2'
bzf = bz2.BZ2File(file)
try:
   tarf = tarfile.TarFile(fileobj=bzf)
   tarf.extractall(working)
finally:
   bzf.close()

File "build_nsis.py", line 94, in <module>

tarf = tarfile.TarFile(fileobj=bzf)

File "C:\OsGeo4W-LINZ\apps\Python27\lib\tarfile.py", line 1574, in init

self.firstmember = self.next()

File "C:\OsGeo4W-LINZ\apps\Python27\lib\tarfile.py", line 2319, in next

tarinfo = self.tarinfo.fromtarfile(self)

File "C:\OsGeo4W-LINZ\apps\Python27\lib\tarfile.py", line 1239, in fromtarfile

buf = tarfile.fileobj.read(BLOCKSIZE)

IOError: invalid data stream

I've double checked my downloaded file and it ok. tools like tar and 7z can actually decompress the tar.

despite the name the archive was gzipped instead of bzip2ed. fixed in 3.1.1-4
