 When simply displaying a contour line vector, the Query Tool (this located
 in the map display toolbar) works fine, i.e. in my case one can access z
 values stored in the related attribute table. Attributes are stored in a
 postgres DB.
 Then I change the display rule for the map, e.g. only showing major
 contour lines, via this 'where' argument :

 {{{
 z % 50 = 0
 }}}

 Now the Query Tool fails, giving this error message :

 {{{
 Traceback (most recent call last):
   File "/usr/local/grass-6.4.3svn/etc/wxpython/mapdisp/mapwi
 ndow.py", line 904, in MouseActions

 self.OnLeftUp(event)
   File "/usr/local/grass-6.4.3svn/etc/wxpython/mapdisp/mapwi
 ndow.py", line 1105, in OnLeftUp

 self.parent.QueryVector(self.mouse['begin'][0],
 self.mouse['begin'][1])

 qlayer = self.AddTmpVectorMapLayer(mapName, cats, useId =
 False)
   File

 line 862, in AddTmpVectorMapLayer

 parg,pval = p.split('=')
 ValueError
 :
 too many values to unpack
 }}}

 Invoking a more "sql-basical" condition (e.g. z > 1800), this error does
 not happen.
