I need a stack and the contents of the Transcript ... I have a guess as to
where this might be coming from, but without a stack I cannot help.

The above was run in Pharo1.4? After the previously reported error?
Presumably the name not found came from an attempt to prime the registry,
but I am suspicious that there might be trouble lurking ...

If you want the _best_ results, I suggest that you start with a fresh 1.4
image, load the Metacello Preview as above, then using `Metacello new`
commands load the rest of the code ... the only way that  you could get a
complaint about Seaside-Tools-Core would be if you've already loaded
Seaside and/or loaded the Seaside configurations ... I don't think this is
a requirement, but if we continue to have issues that aren't explainable,
then I'd like to be assured that we have an image that is not tainted by
partial loads ....

Remember, currentVersion is suspect, especially once you have started using
the Metacello Preview and especially once you've started loading projects
from GitHub ... in your case if [2] completed successfully, then you are
using a version of FileTree that was loaded from Github using
BaselineOfFileTree and ConfigurationOfFileTree has no bearing ...

In tODE the `project list` displays the version for each project, but I
guess I haven't pulled the logic into the Metacello aPI (yet[3]), but the
following will provide better information that using #currentVersion:

(Metacello image
    project: 'FileTree';
    list)
    collect: [ :projectSpec |
      MetacelloProjectRegistration
        registrationForProjectSpec: projectSpec
        ifAbsent: [  ]
        ifPresent: [ :existing :new |
          existing baseName , ' ' , existing currentVersionString , '['
            , existing currentBranchName , ']' ] ]

When two entries are present the baseline is the one that is loaded, so I'd
like to see the result of this expression from your Pharo1.4 image.

Again in GemStone, I'd like to see the result of the above expression, so I
know where we stand...

Ah you've got a handle on the utf8 bytes. Please send me the undecoded utf8
string so that I can figure out what might be going wrong.
