Description

My QGIS3 crashes whenever I execute the following code in Python-Console:

iface.mapCanvas().scene().items()

I have tried in QGIS3.2 and also QGIS 3.4. I work on Windows, and this issue started this week, before that it was working fine. I have tried to re-install QGIS with no success.. Any idea what it could be?

The crash report is the following:

Works ok here. Have you tried with a clean profile and no plugins?

Hi Nyall,

with a clean profile it works fine! Do you know what the issue could be with my previous profile?

could be a bad 3rd party plugin or a legacy setting/config in the profile folder.
