That seemed like a pretty good guess, but it's wrong. I cleaned up the example by removing the SoupServer (relying on connection to gnome.org instead) and removing the GMainLoop (relying on only gtk_main()/gtk_main_quit() instead). Problem still occurs. It's definitely related to whether the web view has a parent. It does not have to be visible, but it does need to be parented so that it's part of the widget hierarchy, or the load never finishes. I have no clue why.

Will attach a revised test that's just a simpler version of what Jan-Michael uploaded.

We can agree that this is weird. :P

Really weird. Why would that happen...?
