Yes, that's a bit weird. Running gsettings-data-convert from module-
gsettings should work fine. I'll submit a patch for doing that. The two
gsettings-data-convert related patches for paprefs can probably be

I already submitted a patch that enables only gconf or gsettings if
both are available. If a distribution really wants to enable both,
that's possible, but in that case it should ensure that at runtime
module-gconf and module-gsettings aren't installed at the same time.
One reason to build pulseaudio with both modules would be to allow
updating pulseaudio before paprefs. An old paprefs version would then
keep working with a new pulseaudio version, and when paprefs is
updated, pulseaudio won't need to be rebuilt with different options. I
don't know if there will be need for that in practice, though.
