Description

Just noticed fTools's Delaunay triangulation broken; when trying to process a points layer, it freezes at 0% and eventually crash QGIS. Possibly another new vector API?

Tried on both windows and linux, both freeze 'n crash.

Commit https://issues.qgis.org/projects/quantum-gis/repository/revisions/9afe76d4d63e57abfbf8b42d2333fde548d78de3 didn't fix this issue.

- On a set of +13,000 points, QGIS chokes and eventually crashes at 0%
- On a reduced set of 655 points, the process freezes at around 50% and eventually QGIS has to be killed

I'm attaching the 655 points set to this issue.

by the way, most of the tools in the vector menu are suffering of serious issues.

Using the attached kml.

  • I get segmentation fault using ftools in the Vector > Geometry Tools > Delaunay Triangulation.
  • But this works with Sextante > QGIS geoalgortithm > Vector Geometry Tools > Delaunay Triangulation.

System: Ubuntu precise latest nightly build.
