Hang when opening bookmarks popover
We have an extraordinarily frequent UI process hang followed by UI process exit that occurs when using the bookmarks popover. It can occur when opening the popover or when clicking the button to open the bookmark properties dialog. I've hit this bug at least 20-30 times in the past hour or so so it's pretty dire. The entire bookmarks popover is effectively unusable right now.
However, it is not a crash. Epiphany does not leave a core dump when it exits. I guess some code somewhere (probably not in Epiphany itself) is calling exit() or _exit() or similar, so it's going to be real hard to track down.
This issue started happening around the same time as gtk#5761 (closed) but I'm unable to verify whether it is the same underlying bug or different because I haven't been able to attach with gdb while epiphany is frozen. It exits too quickly.
