trouble opening an old gnumeric file

[Allin Cottrell <cottrell wfu edu>]

Today I tried to open an old gnumeric file (quite old, from 2000) 
using gnumeric 1.8.3.  The result was not pretty, terminating in a 
crash:

waverley:~$ gnumeric ricardo.gnumeric
Reading file:///home/cottrell/ricardo.gnumeric

Any suggestions on how to fix the old file so it can be read?
Thanks.
