Problems opening ledger file

[Jason Smith]

Hello,

I'm having an issue opening my ledger file. I'm not sure how to proceed
in fixing the issue. I've done some google searches and have looked
through the archives and couldn't find anything that is helpful. Below
is what is showing up in the gnucash.trace file. I'm using GnuCash
2.2.1.

Nations have recently been led to borrow billions for war;
no nation has ever borrowed largely for education.  Probably,
no nation is rich enough to pay for both war and civilization.
We must make our choice; we cannot have both.

Education is a better safeguard of liberty than a standing army.
