FWIW I can reproduce the problem with IDLE and tk_scroll.py:
1) Add a spanish keyboard layout in System Preferences (my normal layout is US
International, matching the text on the keyboard)
2) Select this keyboard using the keyboard menu item
3) Type CMD-^ by pressing "CMD+SHIFT+[" (that is, at the same time press the
keys CMD, SHIFT and the key where [ is on the keycap).
With tk_scroll.py the following output is shown in the terminal:

I haven't (and won't) further investigated this problem, but at least this
should help reproduce the problem. Its likely a Tk problem, but maybe it is
possible to tweak IDLE or Tkinter to avoid a crash.
P.S. The crash does not happen with a US keyboard layout.
P.P.S. SHIFT+[ appears to be how you enter "^" on a spanish keyboard.
