Upgrade Plone 3.3.6 to either Plone 4.3.7 or Plone 5 (Error: 'tuple' object has no attribute 'remove')

I'm attempting an upgrade of an existing site from Plone 3.3.6 to Plone 4.3.7, and then on to Plone 5.0.

The existing site is very small, and has no add-on Products installed (vanilla Plone, vanilla template, etc.) It did have CacheFu installed, but after some earlier obvious errors with that, I removed it prior to the upgrade. I'm simply copying the contents of var/filestorage (Data.fs, etc) from v3 site to v4 site and re-running buildout.

In Plone 4.3.7, when running the UPGRADE option, I see a lot of successful activity, and then the following error at the bottom:

    Upgrade aborted. Error:
Traceback (most recent call last):
  File "/usr/local/Plone4_migration/buildout-cache/eggs/Products.CMFPlone-4.3.7-py2.7.egg/Products/CMFPlone/MigrationTool.py", line 259, in upgrade

    value.remove('Large Plone Folder')
AttributeError: 'tuple' object has no attribute 'remove'

If I skip Plone 4.x and jump right to Plone 5.0, I can't even run the UPGRADE feature, and just get the following error trace on the console:
