Comment (by tmsz):

 Hi,

 This error appear on OS Windows platform only. Offset for import rasters
 can be different on OS GNU/Linux. I think problem is not with raster name
 length.[[BR]]

 When I run t.rast.aggregate, which inner create process (in the source
 code for create new process is called python method
 _subprocess.CreateProcess() on OS Windows platform) with argument which is
 command-line calling g.message command with argument message which is very
 long. On Windows OS platform is command-line string limitation for total
 length of the following command line (last previous link).

 {{{
 #!div style="font-size: 100%"
 short preview, how is g.message called on OS Windows:
    {{{
  "C:\Program Files (x86)\GRASS GIS 7.0.2\bin\g.message.EXE" -i
 "message=granularity_list:
 [<grass.temporal.space_time_datasets.RasterDataset object at 0x040968F0>,
 ...
    }}}
 }}}

 Check the text file (complete g.message command calling) in the attached
 previous archive.
