464712 - two same symbols (double letters) are typed instead of one in case of typing on russian language

Status: RESOLVED DUPLICATE of bug 373071

(Firefox :: General, defect)

Description

[alex]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4

the problem is that when you typing smth using russian (cyrrilic) letters suddenly every one letter start appearing on the screen twice.
for example i write "hi" (lets suppose that is russian cyrrilic input), so in the case when problem takes place on the screen i see "hhii". and if i want
to writedown "hi bro how are you" but NOT "hhii bbrroo hhooww aarree yyoouu" - i must restart firefox, but sometimes this problem can appear so often that the best way to solve it (as temp. solution) is the firefox reinstallation (application uninstallation, removing profile from %appdata% and %appdata%\local settings\; application installation with new profile...).
and as it was mentioned above -after some period of working it returnes back.
the fist time i noticed that problem on firefox v2, than it rebourn in firefox v3 including the latest firefox v3.0.4 that i downloaded today and got the same ubnormal behaviour. 
operating system: ms windows xp pro sp2, windows xp pro sp3

Reproducible: Sometimes

Steps to Reproduce:
