Thanks for quick response.

No HTTP proxy used.

I found out a simpler reproduction, it is to just run WebKit example
browser: /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/MiniBrowser

And, I tested problem with Atril print dialog. First with downgraded
package and it worked fine, then upgraded and Atril crashes ~ one
second after opening print dialog.
