Bug 197653 – [GTK] Crash in webkitWebViewBaseSetEnableBackForwardNavigationGesture

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

We still need to null-check the ViewGestureController there, since it can be called with a running process but not yet attached when using a related view.
