I've had the same issue with javascript.

The cause was the visibility of the widget wich contains the web page
(in my case, a map viewer into a toolBox).

When the widget is not visible (i.e. at launching) the application crash
(alway
with OpenStreetMap and randomly with Google Map api) but never when the
web page
is visible.
