Gramps does not start if the Python 3 version is selected as the default python. The problem is in /usr/bin/gramps, last line: exec /usr/bin/python -O $GRAMPSDIR/gramps.py "$@" If you change that line to read exec /usr/bin/python2 -O $GRAMPSDIR/gramps.py "$@" then everything works fine. Reproducible: Always
Fixed through some configure manipulation. Thanks for the information.
