I'm running python2.3.3 as shipped with Mandrake 10.0 Official. Locale is
ru_RU (KOI8-R). When running python in intercative mode (tested in
KDE's Konsole and Xterm), I get SegFault each time I press almost any
key while a cyrillic character is under cursor.

Say, I type:

>> s = 'GB> 70 G5@B'

Then I move the cursor using arrow keys somewhere to the middle of
the string. Now if I press a letter (no matter english or russian keymap
being active) or backspace, or maybe other keys, the interpreter
crashes. The arrow keys themselves are working without problems.

It doesn't happen if an ASCII character is under cursor.

What version of readline? I don't think this is going to be a Python
bug.

How can I find out readline version?

Ask Mandrake. Mandrake is rpm-based, right? So

rpm -q readline

should work.

libreadline4-4.3-7mdk

So it's 4.3

But if it were a readline bug, wouldn't it mean it should appear in other console
applications? It doesn't, at least in shell.

Hrm. Maybe it's not a readline bug then.

OTOH, I've not heard of a Python bug like this either. Do you
know how to use gdb?

(It's possible that bash uses its own version of readline).

It seems to work for me for same input on ru_RU.KOI8-R locale.
My terminal app is gnome-terminal and tested platforms are:

• FreeBSD 5.3 with readline 4.3
• Debian stable with readline 4.2a
• Debian testing with readline 4.3

Is this still a problem? Can anyone reproduce? If we don't
hear back within a month, this should be closed.

Close enough to a month. Closing due to lack of
information/repeatability.
