It happens when attaching a new web process, because it tries to encode a null SessionState.

#0  0x00007ffff4a40263 in WebKit::WebBackForwardListItem::encode(IPC::ArgumentEncoder&) const () from libwebkit2gtk-3.0.so.25
#1  0x00007ffff4a340d4 in WebKit::LegacySessionState::encode(IPC::ArgumentEncoder&) const () from libwebkit2gtk-3.0.so.25
#2  0x00007ffff4a54ae2 in WebKit::WebPageCreationParameters::encode(IPC::ArgumentEncoder&) const () from libwebkit2gtk-3.0.so.25
#3  0x00007ffff4ac5679 in bool WebKit::ChildProcessProxy::send<Messages::WebProcess::CreateWebPage>(Messages::WebProcess::CreateWebPage&&, unsigned long, unsigned int) ()
   from libwebkit2gtk-3.0.so.25
#4  0x00007ffff4aba790 in WebKit::WebPageProxy::initializeWebPage() () from libwebkit2gtk-3.0.so.25
#5  0x00007ffff4ababbb in WebKit::WebPageProxy::reattachToWebProcess() () from libwebkit2gtk-3.0.so.25
#6  0x00007ffff4abb608 in WebKit::WebPageProxy::loadAlternateHTMLString(WTF::String const&, WTF::String const&, WTF::String const&, API::Object*) ()
   from libwebkit2gtk-3.0.so.25
#7  0x00007ffff4bdd190 in webkit_web_view_load_alternate_html () from libwebkit2gtk-3.0.so.25

I guess EFL is affected as well.
