IDLE will not start.  I have installed python via the
python-2.6-macosx.dmg image found on http://www.python.org/download/.  I
didn't find any resolutions in bugs.python.org, but did note that you
are having some trouble with tk (as discussed in other bugs).  I haven't
tried much to troubleshoot the issue yet other than note that the 2.5
version of IDLE does start.  Below is some info on the problem:

I see the following in my logs every time I try and start IDLE:

Closing this in favor of issue4017.
Check if anything there works for you, or add something new.
