This still has at least two problems:
1. the gconf schema installation is broken, and I don't see an
obvious way to fix it given the error message; I'm inclined
to say that gconf schema installation was intentionally
broken since everything is using gsettings now, but I could
obviously be (very) wrong.
2. the package as a whole may well be broken, but at least the
'seahorse-preferences' binary is broken due to trying to load
symbols from both gtk2 and gtk3 in the same process.
At this point, I'm all out of fucks to give on this one, so maybe
someone with a fresh supply can have a look...
