I can confirm this continues for the launcher 1.5.3 (not sure about lased release).
I also hold a copy from the launcher where this message was spammed as I was trying to join a server.
P.S. Sorry about duplicate comments, I have now deleted them. I was having internet connection problems.
I haven't run minecraft recently much, so I feel I can't effectively answer the above. However what I have noticed is items disappear when you login a 1.8 world with a 1.7 profile loaded. This is probably because the new formats which may not be compatible.
From searches I have found that the items are unreplacable. So for other users; take this as a warning.
I have been constantly having low fps (2-7) with a new world. However today when I ventured off with a boat the fps rose up 97 sometimes (60-80 average). It seems loading new chunks, rather than staying in old boosts the performance. Has anyone else noticed this?
Edit:
Also during the previous low fps I could bearly rotate my view.
I realise I didn't word it well. I meant the other issues which duplicate the same thing. However I also have checked and they were from last year, so they couldn't have been me.
The 2nd crash report is for 1.8.
Is the other bug report caused by publishing from the launcher? If so that may have been me.
Also effects 1.8, however is harder to crash.
Ok, try this:

I have been receiving this error, however before I even join a server.
I can supply a crash report as well (already published it).
Reproduction:
1.Make sure a lan server is running, preferrably by another account and computer.
2.Press the Multiplayer Option
3.Click on the lan server as it appears at the bottom of the list.
4.Hold shift and press the "up" button.
5. (Ocassionally) If this doesn't work try selecting another server or something.
At this stage the launcher should be frozen for a bit and then reopen with crash reporter.
This is as current 1.7.10 , I shall try with the latest snapshot and see how it goes.
Edit:
This still occurs in 1.8-pre3.
Should I make a new report, if this is a different cause to the same error?
I thought it was fixed for me atleast in 1.7.2 and 1.7.1, but then yesterday I logged on singleplayer and a sign was missing. It was the last thing I had placed in a previous session. This happened in 1.7.4, so I don't know whether 1.7.2 was fixed or not.
I have evidence of this bug in snapshots. If I can attach these, just ask. (i.e. version 1.6.4)
Edit:
Upon reviewing the snapshots, they do not display much detail of the bug (however a video would). So these snapshots would be of little use.
I've received this issue in the 1.6.1 release, although it may be by another cause. I use Windows Vista.
Here's something I also thought was related:
http://dev.bukkit.org/server-mods/nocheatplus/tickets/320-erm-some-weird-freecam-bug/
Yes, excellent reproduction Mod Tails, i've tested it, and it work every time. Although I had some trouble geting the boat on the sign.
Edit:
Although it only seems to work for those with the glitch.
I thought this may be related, (i.e. its about a mod to do with this bug):
"Well, basically the way freecam works is you simply stop sending move/look updates to the server. On the client you're still moving about, but the server never gets told that so it thinks you're just standing there. So all you need to do is take the whole if/elseif block that sends out those packets, and put it inside your own if statement checking if freecam is on."

Jonathan, may I ask, what do you mean by "stone silver" vanilla client?
I've had the same problem Eric, although for me it happens out in the open (i.e. fields etc.)
Just to be sure, is this the Problem your talking about: (see below link)
http://www.minecraftsurvivalgames.com/threads/1-3-game-ending-killing-glitch-bug.16114/
Short Description:
"All of a sudden everyone sees my player frozen but i can move but cant do anything and if i drop things they come out of my frozen player and my frozen player can attack from there but u will basically always die."
I also get the 'knockback thing'. The F3 menu and running helps prevent it though, temporarily.
It effects versions 1.3.2, and all of 1.4.
I've had this same problem, its only on servers.

Also note: the glitch has been named the "Freecam Glitch". (this is not a mod)
I have this same problem on single player.
Keeps happening sometimes in 1.10.
Edit: Could a previously 1.9 world (and possibly wolfs) cause this?
