Can't Parse

[JUNIPER]

We just upgraded to Kubuntu 7.1. GnuCash worked fine once, but now, 
during the booting process, I get the msg:

Can't parse the URL /home/steve/.gnucash/books/allfinance.

Then, before closing I then get a "<no file>" window.
Any idea what might be the problem and how it might be solved?
Thanks!
