Description

FLAIR seems to work fine, but crashes when I am trying to inspect the project or work on the input file cards.

Below the message I get:

/Users/iliasefthymiopoulos/FLUKA/flair/flair: line 18: 59279 Segmentation fault: 11 {PYTHON} -O -W ignore {DIR}/flair.py “$@”

Of course, my input file contains geometry errors that I am trying to resolve; however, I believe this comes from FLAIR itself and probably my installation.
