The ftbfs bugs caused by vala and a new gobject-introspection can easily be
fixed (at least in most cases) by switching to valac-0.20 which just got its way
into unstable. I just fixed bug #707378 this way by switching the build
dependency accordingly.
Unfortunately in the case of gedit-valencia-plugin it's not that simple.
Switching to valac 0.20 (debdiff attached) results in the following.
valac -X --shared -X -fPIC --vapidir=. --pkg gedit --pkg gee-1.0 --pkg
gtk+-3.0 --pkg libvala-0.20 --pkg vte-2.90 --pkg gtksourceview-3.0 --pkg

Since I don't know any vala I can't really help in working out what is
going wrong here.
