Summary: python throws an error when unpacking bz2 file

Initial Comment:

I think, when unpacking bz2, an error occurs and windows shows an error about 
"python.exe has encountered a problem and needs to close"

I downloaded the file from the URL given above, and when I tried to
decompress it in a single shot (with bz2.decompress), python crashes. 
Reading the raw bz2 data from file into a string in memory works ok, but
attempting to use bz2.decompress on that data causes the crash.

I could only get this to happen under 2.5.1 on a Windows XP machine (media
center edition); it seems to work ok on OSX (Python 2.5) and Linux (both
2.4.4 and the current trunk).  I will be able to take a closer look at this
tomorrow when I have access to a Windows machine with a compiler on it.

Can you try to take the .tar.bz2 file and unpack it yourself using
Python's bz2 module?
We can then find out where exactly the segfault occurs.
