Or maybe not.
I'm sure I was able to print the value of variables like this:

 except : 
        pdb.set_trace()

run the program:
        error message
        (Pdb) d <return> (not sure why!)
        (Pdb) print dentry.path
        (Pdb) more debugging here

But pdb complains that there are no such variables.  It may be that I had to
add some incantation around the script startup - I just can't remember (and
its frustrating!).

Thanks
Graham
