I compiled today Ephy with WebKitGTK+ 2.5.1 from the tarball that I get from jhbuild with moduleset for GNOME 3.14. I am getting these error messages and then the browser crashes: Received an unexpected URL from the web process: 'file:///usr/share/doc/auto-complete-el/doc/index.html' Received an invalid message "WebProcessProxy.AddBackForwardItem" from the web process. Received an unexpected URL from the web process: 'file:///usr/share/doc/auto-complete-el/doc/manual.txt' Received an invalid message "WebProcessProxy.AddBackForwardItem" from the web process. Bus error
Sounds like you are using a new ui process with an old web process or the other way around.
Are you sure you ran make install in both wk and ephy?
