This also happens if I use python2.4 bootstrap.py && bin/buildout
instead of using my system-wide easy_installed zc.builbout.

And today I see 13 failures and 5 errors on Python 2.5 on 64-bit Linux,
but only 9 failures and 3 errors on Python 2.4 on the same 64-bit Linux.

This is caused by z3c.skin.pagelet 1.0.2, which has a
z3c/skin/pagelet/testing.py with

  TestLayer = ZCMLLayer(
      os.path.join(os.path.split(__file__)[0], 'ftesting.zcml'),
          __name__, 'DemoLayer', allow_teardown=True)

The test runner should verify this during import time and complain
early, instead of crashing in the middle of the run.

I also don't know why this doesn't always trigger the crash.  The test
runner has some sort of a layer cache, that might explain it.

Did that.
