Problem with shelve/gdbm

Hi-

I am having a problem with shelve. The problem I think is really with  
gdbm. I'll write out a file using shelve/gdbm on an amd64 machine and  
then I'll try to read it in on a i386 machine. The result is a 'gdbm  
fatal: read error.' Reversing directions results in the same problem.  
Below are two small programs that get at the heart of the problem:

#test.py##############
#!/usr/bin/env python
import gdbm
print gdbm
storage = gdbm.open('test.pstor', 'c')

storage['test'] = 'a'

storage.close()


#test2.py#########
#!/usr/bin/env python
import gdbm
print gdbm
storage = gdbm.open('test.pstor', 'r')

print storage['test']

storage.close()

#####################################
The result of running test2 is as follows:

<module 'gdbm' from '/---/software/python/lib/python2.5/lib-dynload/gdbm.so'>
Traceback (most recent call last):
   File "./test2.py", line 4, in <module>
     storage = gdbm.open('test.pstor', 'r')
gdbm fatal: read error



It isn't much to go on, but has anybody else had this problem?


Cheers,
Doug
