[GRASS-dev] Error reading raster data for row xxx (only when using r.series and t.rast.series)

[Dylan Beaudette]

Thank you for the clarification Sören.

Any ideas on how r.series could be leaving maps open or otherwise
corrupting inputs in those cases where:

1. there are a lot of maps (>100)
2. method=sum
