Comment (by lutra):

 Hi Radim,
 the first thing I notice is about linux.

 After having compiled trunk, when I open the grass mapset in the qgis demo
 dataset -and then I add the raster that is in there (gtopo30)- qgis (the
 "value tool" plugin to be precise) throws the following


 {{{
 Traceback (most recent call last):
   File "/home/vania/.qgis//python/plugins/valuetool/valuewidget.py", line
 134, in printValue
     self.ymin=min(self.ymin,cstr.minimumValue())
 AttributeError: 'NoneType' object has no attribute 'minimumValue'
 }}}


 then qgis also throws this


 {{{
 Cannot query raster
 Cannot start module
 command: /usr/share/qgis/grass/modules/qgis.g.info info=query
 rast=gtopo30 at demo coor=-1.43995e+06,8.38359e+06<br><br>
 GRASS_INFO_WARNING(5191,1): Reading raster map <gtopo30 at demo> request for
 row -174 is outside region
 GRASS_INFO_END(5191,1)

 GRASS_INFO_ERROR(5191,2): Unable to read raster map <gtopo30 at demo> row
 -174
 GRASS_INFO_END(5191,2)
 }}}


 in both cases when passing the mouse over the raster in the canvas.


 The happens under windows, but not immediately after having added the
 GRASS raster to the canvas. I'll be more precise in the notes that will
 follow this one.
