The incantations above, in my ~/.gnucash/config-1.8.user file, set a breakpoint in the gnc:kvp-option-dialog procedure, which implements some of the function of the GnuCash dialog which appears when "Properties" is selected from the "File" menu. The following pages of this demo show how guile-debugging's "GDS" interface displays the Guile execution stack at such a breakpoint and allows you to step through the code from that point.

To see this in practice, therefore, save the above into your own config-1.8.user, then fire up GnuCash and select "Properties" from the "File" menu ... Next
