Unknown causes of GTK messages in log

[emyoulation]

I did not notice the (gramps.exe:12372): Gtk-CRITICAL **: _gtk_widget_captured_event: assertion 'WIDGET_REALIZED_FOR_EVENT (widget, event)' failed messages appearing in the Console. I was testing (and loving) the new responsiveness in the Context menu appearance. However, I had noticed there were DIFFERENT context menus depending upon which element within a panel was clicked. So I was clicking different elements. (It was a bit odd that a right-click outside the context menu simply dismisses the Context menu, it doesn't initiate a new context menu for the indicated element.) Then I belatedly noticed the pink Gtk-CRITCAL messages in the Console.

Future clicks did not add messages. So I tried closing the Tree and reloading. Then right-clicking some more. And finally did some left-clicks to change the View focus and then tried more right-click context menus. No joy.

So here's the Console log if that helps at all.

The earlier post_create error is a bug in Gramps core.

Regarding:

(gramps.exe:12372): Gtk-CRITICAL **: _gtk_widget_captured_event: assertion 'WIDGET_REALIZED_FOR_EVENT (widget, event)' failed

These are annoying and are a result of how the pop up menu works. In and of themselves they have not caused a problem for me. I've been meaning to experiment to see if the context menus elsewhere in Gramps cause the same asserts sometimes. I suspect so. I need to ask someone more knowledgeable like Nick or Paul about them.
