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:

 {{{
 g.proj -p

 I can post the DEM somewhere if you want
