Riccardo said, this file was edited lately.
When I see those large numbers I guess, it may be that while editing that file 
on amd64, after the NSNotFound change with Gorm, that Gorm did encode some 
garbage in it?

I have seen a similar problem with a Gorm file of PRICE too while testing that.
The problem with GWorkspace only tested on i386 so far, the problem with PRICE 
I have seen on i386 and amd64.

Any idea where this could come from and what to do about it?
I have no clue, I hope others can help. This kind of errors happened
when you had a bogus version number, remember? But here it should be
fine in the gorm file, please check.
I hope other core guys can jump in, describe your configuration more
precisely?

I am able to open GWorkspace's preferences panel on most 32bit platforms
I have: NetBSD Sparc&x86, linux and even OpenBSD (using gcc and the
whole sourcetree built from our repository, not ports). It works also on
linux x86-64.

Philippe asked me to test his SimpleAgenda, there I run into the same problem.
He is using gnustep-core from svn. So I'll try installing gnustep-core from
svn to see whether those failures will vanish.
If yes, this still doesn't help me much to get those Applications running with
the latest releases...

So, I did the promised test, and found with gnustep core from svn, all is 
working fine,
PRICE, GWorkspace, and also SimpleAgenda, at least with regard to the Gorm 
loading problem.
Not much else tested so far. As it seems, their Gorm files were all edited with
gnustep core newer than the latest releases.
So the question I have now, is there an easy way to get them working with
the latest releases to make packagers like me happy? ;)

That is just what I expected to be the problem. If you need to backport some code, this will most likely be the method -decodeArrayOfObjCType:count:at: on NSUnarchiver (and maybe in NSPortCoder as well, if you need interaction with newer code). I am still wondering, why we don't raise an exception in base, when the version found in the archive is incompatible with the version we are running on. But even that change wont help you, as this code would only be in the new code :-(
