BT from gdb, when running epiphany with the env variable G_DEBUG=fatal_criticals

This critical seems, somehow, related with epiphany's "about:overview" tab.

The steps to reproduce are not reliable. Sometimes in a running session I see them all the time and sometimes never.

But, when it is actually happening, a way of forcing it to happen is:
1. Open some "about:overview" tab.
2. From it, open with the secondary mouse button a new tab, from the "favorites" grid.
3. Move from tab clicking in the new opened tab that was loading in the background.
4. Click in the "x" to close that new tab. The focus moves automatically to the previous "about:overview" tab from which the newest closed tab was opened.

In the moment of closing and automatically returning to the previous "about:overview" tab, several CRITICALs appear in the terminal.
