Have you heard anyone complaining? ^_^

I've attached 2 patches (need to be committed together, only for
readability). to fix the ignored property base and some compiler
warnings in gcc 4.4 (and my crazy compile flags). Seems to work here
with the patches, only a lot of errors are printed when a property
does not exist:
xfconf-WARNING **: Initial query for property "/foo" failed: Property
"/foo" does not exist on channel "bar"

Still a bit tricky code IMHO, but it is indeed a problem that needs to
be fixed...
