Description
We seem to be seeing this crash a fair bit from our users and most reported they were trying to interact with checkbox or other UI element in a dialog of our software.
The call stack looks like

Would be good if we can offer the users steps to avoid the crash if it's not going to be fixed. We haven't been able to reproduce the issue locally.
