Page Infomation doesn't work, crashes Epiphany

[Nguyễn Tuấn Đức]

Binary package hint: epiphany-extensions

When I use Page Information extension, it doesn't show any information about the link I currently open. After I close its window, Epiphany close without any warning!

Steps to reproduce
* Activate the Page Info extension
* Go to View > Page Information
* Close the Page Information window

When I run Epiphany from a terminal, I see the following text after Epiphany crashes:
