Here's an evince browser plugin crash in WebKit::NetscapePluginX11::visibilityDidChange. After closing an Epiphany tab, WebKit calls gdk_x11_window_get_xid with a NULL GdkWindow: Thread 1 (Thread 0x7f3255dc6ac0 (LWP 3682)): #0 0x00007f324b294772 in _gdk_window_has_impl (window=<optimized out>) at gdkwindow.c:626 #1 0x00007f324b294772 in _gdk_window_has_impl (window=window@entry=0x0) at gdkwindow.c:627 #2 0x00007f324b2c798e in gdk_x11_window_get_xid (window=0x0) at gdkwindow-x11.c:5542 #3 0x00007f3253f1343a in WebKit::NetscapePluginX11::visibilityDidChange() (this=0x56156e41ec20) at /usr/src/debug/webkitgtk-2.12.4/Source/WebKit2/WebProcess/Plugins/Netscape/x11/NetscapePluginX11.cpp:267 windowID = 0 #4 0x00007f3253cad366 in WebKit::PluginControllerProxy::visibilityDidChange(bool) (this=0x56156e42b230, isVisible=<optimized out>) at /usr/src/debug/webkitgtk-2.12.4/Source/WebKit2/PluginProcess/PluginControllerProxy.cpp:437 There's only one report of this ever happening (and it's mine).
