Missing labels with the new labeling system

Description

Hi,

The new labeling system doesn't display all the labels of a layer, see the joined file for an example using an integer field for labels. The parameters used are free placement and no obstacles, activating colliding and candidate labels modify nothing.

The old labeling system displays them all, I can reproduce this problem with other layers.

The bug is due to topological errors in the polygons, the labels appears when it is corrected (not self-intersection). This behavior is making the use of the new label engine harder on gps data collected with centimetric gps, if the surveyor makes a small wrong move then the data has to be manually corrected to be labeled (automatic cleaning does not give good result).

The old labelling engine works on both uncorrected an corrected data.
