Might have spoken too soon, or different issue. I get the following backtrace only with 1.260 and not 1.240.
To reproduce I simply used the latest Git versions of Glib::Soup and Gtk2::WebKit, and did:

----------------------------
    $view = Gtk2::WebKit::WebView->new;
    $session = Gtk2::WebKit->get_default_session;
----------------------------

and on exit got:

----------------------------
Program received signal SIGSEGV, Segmentation fault.

Let me know if further debugging is needed, or feel free to send patches to try.
