Ronald Oussoren added the comment: Following the instruction in the log message would also be useful, that is, in a shell window:
$ env CA_DEBUG_TRANSACTIONS=1 /Applications/Python\ 2.7/IDLE.app/Contents/MacOS/IDLE With some luck the stack trace will point to the source of the problem. As Ned wrote, that source is probably TkCocoa. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19677> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
