Hi,

GTK+ is not thread safe, so all GTK+ calls must always occur in the main
thread. WebKitWebView is a GtkWidget and accordingly it's only safe to
use from the main thread.

You can use other threads to perform slow operations, then schedule work
to be performed on the main thread with gdk_threads_add_idle() or
gdk_threads_add_timeout() [1].

Hope that helps,

Michael
