Comment 6 for bug 113669

Dan Chen just pointed me to Debian's equivalent of "needs-packaging" and it appears that back when this software was being developed, it only half-worked and would break software (like Evolution) if schemas weren't setup for every single key. Being two years since it was last worked on, those issues obviously haven't been resolved, and I wouldn't be surprised if new incompatibilities crept up in recent versions of GNOME.
