Actually, it only happens when EWebLauncher is closed by pressing the Esc key.

Comment on attachment 184994 [details] Patch Meh, I take it back, I was testing on an empty page which lead me to wrong conclusions. There's something fishy going on with the URL bar, though.

Quick update: the problem actually comes from the fact that we keep some static global font caches in WebCore and do not destroy them. Since evas_shutdown() ends up calling FcFini() if any font has been loaded by the EFL (which is the case for UIs), that function will assert because the Fontconfig objects created by WebCore are still alive. WebKit2 is not affected simply because the UI created with the EFL is not in the same process as WebCore. Since Qt, Pango and Cairo do not explicitly manage Fontconfig's lifetime, I'm proposing doing the same in Evas in <http://article.gmane.org/gmane.comp.window-managers.enlightenment.devel/50676>.
