Check geometries crashing QGIS 3.6

[qgib]

Author Name: Pedro Henrique Caldeira Caliari (Pedro Henrique Caldeira Caliari)
Original Redmine Issue: 21619
Affected QGIS version: 3.6.0
Redmine category:c++_plugins/geometry_checker

---

After running Check Geometries on QGIS 3.6, even by selecting a single vector layer or some of it's features, QGIS is crashing. When it has a considerable amount of errors, a "QGIS has crashed" window appears, while with a "small" amount of errors (230 or so), the algorithm might run normally and then QGIS crashes in less than a minute. Could it be that I'm using layers and files from a QGIS 2.x material? (if I run on all the layers, about 30k errors are reported and 350k+ errors are given as fixed/processed)

If Check Geometries shouldn't be used for layers containing many errors, which tool should I use in it's place for fixing common geometry errors?

Please attach sample data and the exact specific configurations you are using in the geometry checker.

• category_id was changed from Geometry to C++ plugins/Geometry Checker
• status_id was changed from Open to Feedback
• priority_id was changed from Normal to High

Input vector layers: only the attached layer.
Allowed geometries: line, multiline;
Geometry validity : duplicate nodes;
Geometry properties: none;
Geometry conditions: none;
Topology checks: check for duplicates;
Tolerance: 1e-6
Output: ESRI shapefile on temp directory

I am getting the same issue with QGIS 3.6 (and 3.4) even with a clean profile. It's ok in QGIS 3.2

I cannot reproduce with test data on master/Linux Ubuntu 18.10

Fresh installation (3.6.1) but no way out (ok in 3.2). Check geometry plugin (with quite big dataset) makes QGis crash on Windows 10

No more problems, with the provided dataset, here now on 3.6.1 on linux.

spoke too soon: it still crashes. It does when clicking on "ok" after the tool has fixed all the errors found.

does the same happens on 2.18? can anyone test?

I cannot reproduce with QGIS 3.16 with the data. @gioman Do you reproduce the crash?

@lbartoletti no more crashes, please reopen if necessary.
