 Here's how to reproduce:

 {{{
 g.region raster=elevation
 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.aggregate in=A out=B granularity="2 months" method=average
 basename=b_bimonthly suffix=gran
 }}}

 and this is the error I get:

 {{{

 It works fine in 76 rel branch. I am using trunk r73904 in virtualenv with
 python3.
