I get the same segfault: Using https://grasswiki.osgeo.org/wiki/GRASS_Debugging#Python_debugging_with_pdb I found this: GRASS 7.4.1svn (nc_spm_08_grass7):~ > t.list raster ---------------------------------------------- Time stamped raster maps with absolute time available in mapset <user1>: a_beam_rad_08.00@user1 a_beam_rad_09.00@user1 a_beam_rad_10.00@user1 a_beam_rad_11.00@user1 a_beam_rad_12.00@user1 a_beam_rad_13.00@user1 a_beam_rad_14.00@user1 a_beam_rad_15.00@user1 a_beam_rad_16.00@user1 a_beam_rad_17.00@user1 a_beam_rad_18.00@user1 > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/scripts/t.list(182)main() -> if outpath: (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/scripts/t.list(184)main() -> dbif.close() (Pdb) s --Call-- > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(921)close() -> def close(self): (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(927)close() -> for key in self.unique_connections.keys(): (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(928)close() -> self.unique_connections[key].close() (Pdb) s --Call-- > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(1133)close() -> def close(self): (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(1140)close() -> self.connection.commit() (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(1141)close() -> self.cursor.close() (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(1142)close() -> self.connected = False (Pdb) s --Return-- > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(1142)close()->None -> self.connected = False (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(927)close() -> for key in self.unique_connections.keys(): (Pdb) s > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(930)close() -> self.connected = False (Pdb) s --Return-- > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/etc/python/grass/temporal/core.py(930)close()->None -> self.connected = False (Pdb) s --Return-- > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/scripts/t.list(184)main()->None -> dbif.close() (Pdb) s --Return-- > /home/mneteler/software/grass74/dist.x86_64-pc-linux-gnu/scripts/t.list(188)<module>()->None -> main() (Pdb) s Exception AttributeError: "'NoneType' object has no attribute 'path'" in <function _remove at 0x7f81b64a68c0> ignored Segmentation fault (core dumped) Interestingly, there is no "path" at all in scripts/t.list.
