        Hi,
that's a new behavior of the WebKitGTK. Evolution used to have one
WebKitWebProcess for the viewing and one for editing, being shared
between all the WebView widgets. When you are talking about it, I
vaguelly recall the WebKitGTK developers mentioned some change to avoid
process sharing.

The backtrace you sent (in a previous message of this thread) shows the
WebKitWebProcess idle, waiting for instructions.

This is suspicious. In that case I'd blame WebKitGTK process doing some
odd thing while starting itself. I suppose you get a similar behavior
with another WebKitGTK application, like Epiphany, when opening an
empty tab or anything like that. I've no idea how to analyze this,
checking what a foreign process does while loading is a problematic
thing. Maybe try to downgrade the WebKitGTK? By the way, what version
do you use, please? I know you've the latest Evolution, you've probably
the latest WebKitGTK as well, which might be 2.36.x.

        Bye,
