Every time I try to run a GRASS command I receive the following error: "Oooops! The following output layers could not be open".
Actually the same problem happens with other GRASS commands and even with SAGA commands.

When using Processing (ex Sextante) is suggested to chenge the options and make the module window stay open after the module run, this way you will be able to see the complete module log.
In this case the problem is that your raster is not georeferenced, this is easy to understand because qgis asks for the CRS when you load it, and there is no world file (or at least you haven't provided it).
The r.thin log then shows a message that helps understand
GRASS_INFO_WARNING(28200,2): G_set_window(): Illegal latitude for North
probably because the tools expects the raster to be correctly georeferenced.
