[GTK] REGRESSION Reproducible segfaults since upgrade of 2.4.8 to 2.4.9

• Component: WebKitGTK
• Status: NEW ---

We're using the Gtk3::WebKit Perl bindings of WebKitGTK+ in our web application's test suite and since the upgrade to 2.4.9 from 2.4.8 (openSUSE packages) we get reproducible segfaults in pretty much all tests that use WebKitGTK+. The stack traces all look like this:

Please tell me, how I can help solve this.
