I always log off using the bed now, sometimes it does the flash.. No matter what if I check the bed after logging back in there is an item, food for longer periods - crystals for only a few hours, but I have never seen that text. Like I said I am using default settings so I would think it would fall under something that is there by default. I will look at the log settings and see if there is anything I can check that looks promising.

Is it ONLY when you get get the particle effect when you stretch your arms that the text appears?
