Using Python3.1 built from svn, on RedHat EL4, with Tcl/Tk 8.5 built
from source.

Traceback:

----------------
The list of completions appears just before the crash. I can't tell
whether the error occurs within tkinter or IDLE.

If I find out where to put the try/except I'll submit a patch.

On IDLE 3.0, win xp, cntl-space brings up a selection box with known
names to select.  What was your actual input?

Yeah, I know that's what it's supposed to do.  It does pop up the list
of names, but then crashes.

It happens no matter what has been input, even on an empty window.

However, if it works for everyone else, maybe I built Tcl wrongly.

This is a duplicate, see issue1028.
