I thought I'd provided what was needed or is it up to me to change the status? I've put it as confirmed... I suspect this is the same root cause as bug 421456?
I managed to reproduce it locally. I have started to look on it.
The error was caused by a wrong deletion of child menus in Breadcrumb widget. It was introduced at my fix of the widget, which is not at upstream yet. I concluded the fix and published a new package. I also fix the merge request for the upstream
