New description:

 When running any expression with G7:t.rast.algebra in trunk, I get ERROR:
 Wrong type of input. Here's how to reproduce:

 {{{
 # NC location:
 g.region raster=elevation -p
 for map in `seq 1 10` ; do r.mapcalc "prueba_${map} = ${map}" ; done
 t.create output=A type=strds temporaltype=absolute title="test"
 description="test"
 t.register input=A maps=`g.list rast pat=prueba* sep=, map=.`
 start="2000-01-01" increment="1 months" -i

 t.rast.algebra expression="test = (A[1] - A[0]) / 2" basename=test
 suffix=gran
 t.rast.algebra expression="test = A * 2" basename=test suffix=gran
 }}}

 Both algebra commands yield the following error:

 {{{
 ERROR: Wrong type of input A
 Traceback (most recent call last):
   File "/home/veroandreo/software/grass7_trunk/dist.x86_64-pc-linux-
 gnu/scripts/t.rast.algebra", line 132, in <module>
     sys.exit(main())
   File "/home/veroandreo/software/grass7_trunk/dist.x86_64-pc-linux-
 gnu/scripts/t.rast.algebra", line 124, in main
     pc = p.parse(expression, basename, grass.script.overwrite())
   File "/home/veroandreo/software/grass7_trunk/dist.x86_64-pc-linux-
 gnu/etc/python/grass/temporal/temporal_raster_algebra.py", line 112, in
 parse
     self.parser.parse(expression)
   File "/usr/lib/python2.7/site-packages/ply/yacc.py", line 331, in parse
     return self.parseopt_notrack(input, lexer, debug, tracking, tokenfunc)
   File "/usr/lib/python2.7/site-packages/ply/yacc.py", line 1118, in
 parseopt_notrack
     p.callable(pslice)
   File "/home/veroandreo/software/grass7_trunk/dist.x86_64-pc-linux-
 gnu/etc/python/grass/temporal/temporal_raster_algebra.py", line 137, in
 p_ts_neighbour_operation
     maplist = self.check_stds(t[1])
   File "/home/veroandreo/software/grass7_trunk/dist.x86_64-pc-linux-
 gnu/etc/python/grass/temporal/temporal_algebra.py", line 1226, in
 check_stds
     self.msgr.fatal(_("Wrong type of input " + str(input)))
   File "/home/veroandreo/software/grass7_trunk/dist.x86_64-pc-linux-
 gnu/etc/python/grass/pygrass/messages/__init__.py", line 269, in fatal
     raise FatalError(message)
 grass.exceptions.FatalError: Wrong type of input A
 }}}

 Is this related to the python3 encoding issues? It works fine in 76
 relbranch.
