This sounds like a BBB bug. Please file a bug collector entry.

If you want to be extra helpful, you could provide a unit test:

* Get a subversion checkout of Zope 2.10:

   svn co svn://svn.zope.org/repos/main/Zope/branches/2.10

* If you look in Products/PageTemplates/tests, there are two 
directories, 'input' and 'output'. Place a PageTemplate file into 
'input' and the expected output into 'output'.

* Add a test case in testHTMLTests.py

* Attach the output of 'svn diff' (after having executed 'svn add' for 
the newly created files) to the collector entry.

This will increase the speed with which this issue would be 
reproduceable and therefore fixed immensely :).
