[GRASS-dev] temporal modules cannot open database

Hi Luca,
i did not change the database structure of the temporal framework recently.
The exception seems to be from the sqlite3 backend, hence it should
not be related to different temporal database formats.

Can you access the database with the sqlite3 command directly?

sqlite3 /grassdata/latlong/ecad100_climate/tgis/sqlite.db

Best regards
Soeren
