I found the problem. The path references in GRASS 6.2 libs have an extra 
(non-existent) directory:

/Applications/GRASS.app/Contents/Resources/grass-6.2.1/lib/libgrass_gis.dylib

The libs in 6.3 don't:

/Applications/GRASS.app/Contents/Resources/lib/libgrass_gis.dylib


If I create the following link for GRASS 6.2:

ln -s . /Applications/GRASS.app/Contents/Resources/grass-6.2.1

QGIS can load shp files without crashing and without starting GRASS.


QGIS is probably working ok inside GRASS 6.2 because GRASS has already 
loaded the libraries and QGIS doesn't need to use the path info to find 
them.
