The following code is the smallest (I think) that triggers the bug:

============ __init__.py ===================
import quixote
quixote.enable_ptl
from ptlerror import ptlerror as _q_index
_q_exports = ['_q_index']

============ ptlerror.ptl ====================
import UserDict

def ptlerror [html] (request):
    #dct = {'a': 1, 'b': 2, 'c': 3} # works
    dct = UserDict.UserDict()
    dct['a'], dct['b'], dct['c'] = 1, 2, 3
    dct['a'] # works, prints 1
    '%(a)s, %(b)s, %(c)s' % dct # fails


The following code *works* (import this instead of ptlerror):
============= noerror.py ===================
import UserDict

def noerror(request):
    #dct = {'a': 1, 'b': 2, 'c': 3} # works
    dct = UserDict.UserDict()
    dct['a'], dct['b'], dct['c'] = 1, 2, 3
    dct['a'] # works, prints 1
    return '%(a)s, %(b)s, %(c)s' % dct # works

Finally, note that the code fails in a ptl file even if the string
substitution is done in a function imported from a pure python module.

e.g.,

def anothererror [html] (request):
    pythonmodule.dostringsubstitution(string, dct) # fails
