Crash when using the identify tool in the "layer choice" mode #25310

qgib · 2017-11-07T15:44:43Z

Author Name: Andreas Neumann (@andreasneumann)
Original Redmine Issue: 17413
Affected QGIS version: master
Redmine category:gui

In current QGIS master (07cef67) - when I use the Identify tool with the "layer choice" mode and "Automically open form if single feature is hit" - QGIS crashes just after the layer choice context menu shows up and before the form would show.

Crash dump:

I should add that the Identify tool works fine if I change the mode from "Layer choice" to "active layer only".

Applied in changeset dc7ec1e.

done_ratio was changed from 0 to 100
status_id was changed from Open to Closed

Author Name: Jürgen Fischer (@jef-n)

description was changed from In current QGIS master (07cef67ead) - when I use the Identify tool with the "layer choice" mode and "Automically open form if single feature is hit" - QGIS crashes just after the layer choice context menu shows up and before the form would show.
