tf = tarfile.open(mode = 'w|gz', fileobj=fileName, 
bufsize=20*512)

The following text says how many bytes tarfile writes to
the 'fileName.write' function. Notice that when closing
the tarfile it writes way to many bytes! This happes
just sometimes. Some directories might work, other
might not.

...
write len: 10240
write len: 10240
Closing archive
write len: 24815 # Somthing is wrong?
write len: 4
write len: 4

The close() method just writes the contents of self.buf to the file without
breaking it up into blocks.

Please try the attached patch and let us know if it fixes the problem.

I've committed my fix as rev. 1.10 of tarfile.py.
