After upgrading my installation to 3.4.2 (Win10) I tried the feature
again and run into the following problem:
I have a layer open (tested with *.shp *.gpkg and PostGIS), set the
desired digitizing setting in the layer-options and forcefully add a
topological error.
What then happens is that the validation finds the error, therefore
the layer can not be saved, but the panel does not open.
The log messages say:
- 2018-12-03T11:06:33     INFO    Geometry Validation : Running
geometry validation checks before saving…
- 2018-12-03T11:06:37     WARNING    Could not save changes. Geometry
validation failed.

Am I missing any prerequisite which is necessary? I tested on fresh
layers/projects.

Cheers
