 When trying to drop an existing table, PyGRASS crash.

 The table is created as follow:

 {{{
 l_junc = Link(layer=LAYER_JUNCTION, name=KWD_SECT_JUNCTION,
                 table=vect_map.name + TN_JUNCTION, key='cat')
 t_junc = l_junc.table()
 t_junc.create(COLS_JUNCTION)
 }}}

 When trying to drop the table or rewrite it:
 {{{
 if t_junc.exist():
     t_junc.drop(force=True)
 }}}
 {{{
 t_junc.create(COLS_JUNCTION, overwrite=True)
 }}}

 It gives the following error:
