[GRASS-user] FreeBSD-Grass7 can't start

[Pierre Stévens]

When try to launch Grass70, this appear :

Traceback (most recent call last):
  File "/usr/local/bin/grass70", line 1143, in <module>
    load_env()
  File "/usr/local/bin/grass70", line 659, in load_env
    if not os.access(grass_env_file, os.R_OK):
TypeError: coercing to Unicode: need string or buffer, NoneType found

Searched on the web but no solution found.
Anyone an idea ?
