tags 886052 + fixed-upstream thanks You are probably aware that GSettings support is available in the upstream Git repository. I successfully built the master branch and couldn't detect any problems (except that old settings are not migrated), although I can't test properly as I don't have a DVD.
Unfortunately this migration (plus some other major refactoring) caused ABI break but the SONAME wasn't bumped. Some libraries disappeared entirely, others were renamed and the API changed significantly. Patches for the GSettings switch are not cherry-pickable because a large chunk of the history is lost. But even if they would, they would still break the ABI beacuse of the way GConfClient is wrapped in another object (OGMRipSettings), with a non-trivial abstraction layer around profile parsing/loading and mapping the elements to the corresponding GConf keys. So you might want to ask your upstream to make a new release with SONAMEs of all libraries bumped. Alternatively, package a snapshot of the Git repo and install all libraries as private. There are no rdeps in Debian and AFAICT all binary packages can be merged into one (ogmrip-plugins is particularly useless because ogmrip depends on it).
