Hello everybody,

My app (Nuvola Apps Runtime) faces the issue of instability of Adobe
flash plugin [1] in WebKitGTK+ 2.16.x (including 2.16.4). The Flash
plugin ( usually loads fine for the first time, but any
subsequent attempt to load a flash object fails with following error
messages. Do you have any clues what's wrong? Thanks.

(WebKitPluginProcess2:82): GLib-GObject-WARNING **: cannot register
existing type 'CustomSignalsUnix'
(WebKitPluginProcess2:82): GLib-GObject-CRITICAL **: g_object_new:
assertion 'G_TYPE_IS_OBJECT (object_type)' failed
(WebKitPluginProcess2:82): GLib-GObject-WARNING **: invalid (NULL)
pointer instance
(WebKitPluginProcess2:82): GLib-GObject-CRITICAL **:
g_signal_emit_by_name: assertion 'G_TYPE_CHECK_INSTANCE (instance)'
