Thanks for that - I never managed to fix it, but as I only used PTL in one
place, I got rid of it and then did not enable PTL which at least bypassed the
problem.

Futher to my own post, the error is triggered with the FAVICON...decode()

site-packages/quixote/demo/root.ptl

python2.6/encodings/__init__.py (line 100) (forcing the error, I think).
I don't really get what is going on here, but I have the same issues.
It's more than just encodings, anything which uses import hooks seems
to hit this.
A total hack which does work around this is changing ptl_import.py:133 to
be: --
def import_wrapper(name, globals={}, locals={}, fromlist=[],
level=-1): return cimport.import_module(name, globals, locals, fromlist)
__builtin__.__import__ = import_wrapper
--
but I don't know the negative impact (esp. of dropping the level
argument). Presumably the cimport.import_module should just implement
the expected interface, but I wasn't up for a real patch. :)
We have this problem in w.c.s (http://wcs.entrouvert.org), I use this
version of your work around, just after calling enable_ptl():

enable_ptl()
import sys
# Make ihooks works under python-2.6, problem is that ihooks is broken AND
# deprecated, and so will be removed in python-3.0 without being repaired
# before and there no transition module.
# The exact problem is that the ihooks __import__ implementation does not
# handle the last argument 'level', which is used to do 'relatives' import
if sys.version_info >= (2, 6):
import __builtin__
import ihooks
__old_importer = __builtin__.__import__
__very_old_importer = ihooks.current_importer.save_import_module
def __import_wrapper(name, globals={}, locals={}, fromlist=[],
level=-1):
if level == -1:
return __old_importer(name, globals, locals, fromlist)
else:
return __very_old_importer(name, globals, locals, fromlist,
level)
__builtin__.__import__ = __import_wrapper
