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

[Victor Olaya]

The problem is not in the script itsefl

The problem that was reported is caused by the r.drain algorithm
having a multiple input of vector files. That is used by very few
algorithms, and there is a bug in the way those multiple inputs are
handled that we hadn't see before. I have it fixed and will push the
change to the repo today, along with some other minor changes.

thanks for you help!
