Happened while going back in navigation (and current page was not fully loaded).

I don't see the problem... it's really odd that eolie is creating a new WebKitWebContext during a navigation, but it should have its own separate WebKitFaviconDatabase with its own separate icon database thread. I see an icon database thread is running already, but that should not be concerning because it should be separate.

Eolie does not create a new WebKitWebContext during a navigation, only when creating a new webview.

I see WEBKIT_POLICY_DECISION_TYPE_NEW_WINDOW_ACTION in the log so I guess that maybe clicking on the back button happened while current view was creating a new WebView, no?

[Cédric Bellegarde]

Ok, I'm no sure when I'm calling set_favicon_database_directory() from a new WebKit2.WebContext().

In Eolie, each webview own a context so I'm able to change cookie manager persistent storage => Profiles like in Firefox.

Disabled feature in Eolie until this one get a fix.

Can confirm that crash comes only from this function:

set_favicon_database_directory()

Looks like WebKit2GTK really needs this to be called only one time.

Not an issue for a normal browser but Eolie was creating a Context per WebView allowing me to have differents cookie managers per WebView (profiles like in Firefox)

It's not a blocking issue but it was a cool feature from Eolie:

- Go to google.fr => disconnected from google
- Go to plus.google.fr => connected to google
- etc...
