2.0.4 Backtrace on Start-up (99% solved)

[Kevin Kleinfelter]

GnuCash 2.0.4 is crashing on start-up.  Built and run on Fedora Core 5, with
Guile updated to 1.8.1.  Backtrace is shown below.

If I comment-out line 1ine 118 in
/usr/share/gnucash/guile-modules/gnucash/report/report-gnome.scm, GnuCash
starts.  I have two questions:
1. How do if fix the problem?
2. What functionality am I losing by commenting-out that line?

TIA!
