karl twill test failure under Python 2.6

[Tres Seaver]

When running inside a trunk checkout of karlsample built using Python 2.6, there is one test failure which does not occur under Python 2.5:

 $ pwd
 /home/tseaver/projects/agendaless/OSI/karlsample/src/karl
 $ ../../bin/python -V
 Python 2.6.4
 $ ./test_all
 ...
 Oops! Twill assertion error on line 15 of '/home/tseaver/projects/agendaless/OSI/karlsample/src/karl/karl/twilltests/files/files_aved.twill' while executing

   >> find ${test_file}

 no match to 'test_file782970'

Tres, you want this one? Alternatively, you could close it (you were the original reporter.)

[Tres Seaver (tseaver)]

The test actually shows that the reference manual views are all broken
under Python 2.6 due to a bug in Chameleon 1.1.1: the new 'next' builtin
in Python shadows the value passed from the view.

Workaround committed in r5447, renaming the passed variables 'previous_entry' and 'next_entry',
and updating the snippets macro accordingly.
