called from a couple places in libgis and g.mapsets, but I don't know
how it fits into init.sh.

I'm not sure how it's broken. For me, an invalid mapset works as it
should - it shows an error and brings up the select mapset (GUI or
text) dialog. I tried it for when the whole database path is
invalid, when the location is invalid, and when just the mapset is
invalid. The only errors I get are "LOCATION << ... >> not
available" or "MAPSET ... not found".
The only things that are run in the OSX startup (and for the .app
startup only, not with a basic unix build) are a couple scripts to
build the addon help index and menu files, and they don't need a
GRASS session or run any GRASS commands.
