[Qgis-user] r.drain doesn't work

[Sławomir Bienias]

Hey, everyone..
I have a problem with r.drain in QGIS 2.0.1.
I need to use r.drain tool from Geoprocessing tools. But when I want to use
it, while I have loaded some vector layers (esri shp), Python shows me some
error (below).
"Funny" thing is, when I have loaded only raster files, r.drain works
(r.drain window shows up). Next "funny" thing is, all... ALL of the other
tools work just great. Only r.drain have a problem...

The same problem is on Windows 7 64 bit (osgeo4w installation) and Ubuntu
13.04 32 bit (ubuntugis-unstable ppa).

I noticed, that error is related with shape type (if shapetype ==
QGisLayers.ALL_TYPES or layer.geometryType() in shapetype: TypeError:
argument of type 'float' is not iterable), but I don't know where problem
is and how to solve it...


Below is Python's log error (Windows 7):
