This issue has been identified by rworkman. The issue is happening during the doinst.sh of the package.
The current workaround is to perform the following:
/usr/bin/glib-compile-schemas /usr/share/glib-2.0/schemas >/dev/null 2>&1
This will resolve the issue. I know Pat and rworkman have discussed it, and will get fixed.
Reading my logs, I see the discussion mentioning this occurs during fresh install of -current.
