#3682: t.rast.algebra: Error wrong type of input
----------------------------+-------------------------
 Reporter:  veroandreo      |      Owner:  grass-dev@…
     Type:  defect          |     Status:  new
 Priority:  normal          |  Milestone:  7.8.0
Component:  Temporal        |    Version:  svn-trunk
 Keywords:  t.rast.algebra  |        CPU:  Unspecified
 Platform:  Unspecified     |
----------------------------+-------------------------
 When running any expression with G7:t.rast.algebra in trunk, I get ERROR:
 Wrong type of input. Here's how to reproduce:

 {{{
 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:

 {{{

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