cache_detail page gives TypeError exception

[jfcgauss]

I have programmatically imported a directory tree of text files, with a directory tree depth of 4, up to 200 folders total, and more than 23 thousand text files into my Plone 4.1.2 site. More than 25 thousand tags are also imported from those documents.

Navigation and load times of pages is excellent, tags are working nicely, search form works great. But when I click on the edit link on the green edit bar to edit any of those pages, it takes 5 minutes to see the edit page with tinymce, and python executable goes crazy with %100 cpu during this 5 minutes. Debug console does not show any problem at this point.

While trying to debug this problem I was suggested to check cache details in Zope ZMI, so when I visit Control_Panel/Database/cache_detail I get the following traceback (cache_extreme_detail link works, these links are at Control_Panel/DebugInfo/manage_main):

  Module ZPublisher.Publish, line 126, in publish

-> return '\n'.join('%6d %s'%(count, name) for count, name in detail)

I have Plone 4.1.2, Zope2 2.13.10, Python 2.7 on Ubuntu 11.04 desktop system (a typical custom buildout, not from the Plone 4.1.2 installer at plone.org)

my python is the system's python, which reports itself as version 2.7.1+
