Since update of qgis 2.10, it seems that the combine method doens't work as it did in 2.8
when you try to combine several polylines (an union of road sections) you obtain a multipolyline object containing as many polylines as the number of sections. ITt doesn't try anymore to generate a single polyline if the lines are adjacents
It works with previous versions of Qgis (2.8 for example)
It's blocking because, my plugin build isoband based on an union of simple polylines that were combined as a polyligne converted after in polygon.
Now in Qgis, it's impossible to convert into polygon as the multipolyline contains as many sections as the number of single polylines and it is not closed.
