Difficulty with apps-utils

[Aaron Laws]

I have made several changes on my branch to avoid kvp parsing keys. The
last change I made removes the functions that take char*, but the unit test
suite does not pass. All tests pass except app-utils which fails with the
strange error:

(./test-app-utils:6860): gnc.module-WARNING **: Could not locate module
gnucash/app-utils interface v.0

You can see my code at

Can anyone reproduce the problem? Any suggestions?
