I have just added from the exp tree (unused/ section) a module
from Huidae Cho:

It is not activated in the compile list due to it's freetype dependencies,
but may be a good starting point for further developments.

In general you should give
a try. It supports a large range of formats. But, first, you may
try to zoom the raster map:

g.region rast=imported_map
d.rast ...
d.histogram ...

All GRASS raster commands shall be region sensitive.
Then: file system full? I had such related problems with i.rectify,
not mentioning that the .tmp/ was temporarily flooded...

Best regards
