Comment(by cmbarton):
Markus,
Turns out my map is in Lambert Equal Area. My student's map is in Lambert
Conformal Conic and gives the same result. A geotif of the DEM is 3.9 MB,
which far exceeds the 256 Kb limit of the bug tracker. However, the world
file for r.out.tif is
{{{
999.420668933852198
0.000000000000000
0.000000000000000

4927643.608154466375709
3452811.268273706547916
}}}
...and g.proj gives the following:
{{{

I can post the DEM somewhere if you want
