Bug ID: 166568
Summary: [GTK] ASSERTION FAILED: !source || is<Target>(*source)
on talkgadget.google.com
Classification: Unclassified
Product: WebKit
Version: WebKit Nightly Build
Hardware: PC
OS: Linux
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit Gtk
Assignee: webkit-unassigned at lists.webkit.org

CC: bugs-noreply at webkitgtk.org
This coordinated graphics assertion is reproducible by clicking the video conference button on https://talkgadget.google.com in Epiphany. Both the original browser tab and the new tab created when clicking the button display the crash error page, but it's just one crash because the new webview is related (sharing the original web process):
