Query window and non-english text

Hi!

Thank you for the program!

I found one strange bug in Query window.
If you type Russian letters in it and then use cursor movement key - arrows
or backspace or delete, after you cannot type in Russian any more. You can
press letters on keyboard but nothing happens in the window. If you press
Space or switch to English and press any symbol - then you can type ahead.
After that you can switch back and type Russian letters too.

I have tested it with another languages, for example Azerbaijani. The
problem occurs only with non-latin simbols, such as ı, ə, ş. Symbol ö which
also presents in German works well.

My locale is: ru_RU.UTF-8.
Keyboard layouts: Russian, USA.
PgAdmin: 1.10.0 (aug 17 2009, rev: 7945:7946) installed from repository.
Ubuntu 9.10 Karmic Koala.

Thank you!
