Veo exactamente lo mismo. Anoté la hora (09:35:25) y encontré esto en la Consola:

Parece que tiene que ver con algo llamado "getattrlist".
Aquí hay un enlace que puede ser de ayuda:

Dicho esto, todavía no sé realmente qué es esto, pero ahora sé que no soy el único con este problema.
Sé que esto probablemente no sea de mucha ayuda. Si averiguo más, volveré a publicar.
