If you have a .grassrc6 file that has a set gisdbase, location, and/or

crash on

The only fix is to either make the gisdbase, location, or mapset
directory
that is listed in .grassrc6, or directly edit .grassrc6 to change
or remove
the offending line.
Ah, yeah, that's an annoying one. Though the text and TclTk GUI
don't quit, just notify you of the problem.
Init.sh needs to trap this kind of error--or maybe better just
ignore it. If
any of these files is not present, GRASS should simply go to either
a) the
initial text based startup screen if the text interface or no
interface is
selected in .grassrc6, or b) go to the GUI for selecting
gisdbase/location/mapset as if the gisdbase/location/mapset line
was missing
from .grassrc6. In any case this should not cause a crash.
Part of the problem, specifically for the OSX app startup, is that
double-clicking the app doesn't give you the option to start directly
into a mapset, like you can do with 'grass6 /path/to/location/mapset/
map' from the command line, or adding -text to the startup command,
so it makes editing .grassrc6 necessary to correct problems.
I just thought of one thing I can do for the app startup - drag-n-
drop. I can have the AppleScript app take a folder dropped onto it
as the '/path/to/location/mapset/map' option. I didn't use /path/to/
location/mapset/map much in the past, so it didn't occur to me to use
drag-n-drop in the app ^_^
The selection of text/gui startup I deliberately avoided in the app
startup, because I didn't want a dialog at startup every time, like
Lorenzo does in his binary. I wonder if I can get AppleScript to
intercept a modifier like shift or option at startup, hmmm...
