Comment 1 for bug 1391939

I do not get this, but I think it is due to a race between the creation of the view and the updating of the icons. When initialized, GOF.Files have an icon size of -1. If the icons get updated before their actual size has been set then this error would result. As this does not seem to have any visible effect, other than the error messages, I have just guarded against calling this gof_file_update_icon_internal function with an invalid size.
