Terry J. Reedy added the comment: It seems like a logic error to try to remove something that is not there. But it is not obvious from the traceback that your problem has anything to do with *opening* a file. Unbinding should only happen when *closing* a file. So I suspect this is a different issue.
Please 1. copy and paste the 'sign-in' line that looks like this: "Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:57:17) [MSC v.1600 64 bit (AMD64)] on win32" 2. add the OS version (like 'Win 7') 3. say *exactly* what you do and what happens when. In particular, do you get the traceback when you close a file? Or only when you actually press the [Open] button. Try different python files to make sure it is not a problem with the specific file. Does your IDLE otherwise seem to run normally? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10365> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
