Comment(by sbl):
Some variant of the same problem I guess:
On Ubuntu I get no tiles listed:
On my Windows box I get this error-message:
GRASS 7.0.svn> r.tileset sourceproj="+proj=utm +no_defs +zone=33
+a=6378137 +rf=298.257223563 +towgs84=0.000,0.000,0.000 +to_meter=1"
maxcols=25000 maxrows=25000 overlap=10
sh: r.tileset: command not found
On my Ubunut box no tiles are printed at all:
GRASS 7.0.svn (Norge_33N_WGS84):~ > r.tileset sourceproj="+proj=utm
+no_defs +zone=33 +a=6378137 +rf=298.257223563 +towgs84=0.000,0.000,0.000

Looks like a declaration of floating type variables I necessary, when the
tile_bbox w,s,e,n coordinates are calculated.
Furthermore, the bboxesIntersect() method does not work properly.
The provided patch should fix these issues.
But there will be still a rounding oddity, because my regions n,s,e,w have
no digits, while the tiles get some:
