LargePositiveInteger(Object)>>error
http://code.google.com/p/pharo/issues/detail?id=3534

It was already discussed here:

http://lists.gforge.inria.fr/pipermail/pharo-project/2011-January/039447.html

but I havent found an issue yet.

 From time to time I now also get the following error when opening the
world menu (the menu with the help icon is red crossed due to display error)

I use the latest prebuilt Cog VM

Here is the stack:

VM: Win32 - IX86 - 5.1 - Croquet Closure Cog VM [CoInterpreter  
VMMaker-oscog.45]

Comment #1 on issue 3534 by [hidden email]:  
LargePositiveInteger(Object)>>error
http://code.google.com/p/pharo/issues/detail?id=3534

The problem with this bug is that I was hit by it 7 or 8 times since using
the Cog VM. Anytime when opening the world menu.

Unfortunately it is hard to reproduce manually, I can open the world menu  
afterwards without any problem.

The problem I see in the debugger is that instead of returning a Color  
instance (which would understand #pixelValueForDepth:) a large positive  
integer  4278190081 is returned from the expression "(colors at: i)" in the  
method ColorForm>>colormapIfNeededForDepth:

Didnt have the problem with the latest Cog but it may still be there ...

Suggest to move it to 1.3. (we deliver 1.2 with standard VM, dont we?)
If we see it again we can patch 1.2 anyway.

Torsten, can you check if this is the same bug that Mattew reported to  
Eliot? It seems the same bug, in such case, it is a Cog bug and Eliot said  
he was going to release a new VM during the weekend
