Judging from these traces, some client code is passing an invalid GtkImage pointer into indicator_image_helper_update(). Even if we're not sure who the caller is, we can safeguard against crashes like this somewhat by adding a GTK_IS_IMAGE test to the image argument that gets passed in.
It would be better to find the client code that's passing in an invalid GtkImage, but none of the Stacktraces have that information.
