[issue5492] Error on leaving IDLE with quit() or exit() under Linux

[Ger Luijten]

New submission from Ger Luijten <gcjm.luijten at gmail.com>:

Hello developers,

Found a small error when using IDLE Version 3.1a1 under Kubuntu Linux
8.10 in the terminal.
Kubuntu is fully updated and no installation errors for Python 3.1a1.

See the listing from my installation notes below.

Greetings, Ger


Let's see if IDLE works, by starting it in the terminal:
$ idle

IDLE works in the new Python version 3.1a1, but there is an error!

When leaving IDLE with quit() or exit() and clicking the OK button for
the question 'The program is still running! Do you want to kill it?
there's the errors listed below, that does not occur when leaving IDLE
with Ctrl-D instead of quit():
