#33 — Plone Large Folder breaks install in plone4.0b4

installing plonetruegallery on a plone4.0b4 site(currently there is only the soft release available: http://dist.plone.org/release/4.0b4-pending/)
i get the following error:


  Module Products.CMFQuickInstallerTool.QuickInstallerTool, line 512, in installProduct
   - __traceback_info__: ('collective.plonetruegallery',)
  Module Products.GenericSetup.tool, line 330, in runAllImportStepsFromProfile

ValueError: unknown meta_type ''




i can think of 2 possible solutions:

A) use separate profile for plone4 and plone3
http://dev.plone.org/collective/changeset/118835
http://dev.plone.org/collective/changeset/118834

or B) do not use GS types/Large_Plone_Folder.xml
but add the available view via python code in exportimport.py only for ploneversion < 4
