Bug#456171: locale issue

[Leonardo Canducci]

This bug should be somewhat related to locale settings.
I confirm the bug. I'm running sid with italian locale
(LANG=it_IT.UTF-8) and see the same error. If I type: 
LANG=C xchat-gnome
xchat-gnome starts in english with no errors.
this happened before with previous versions and has been fixed. ubuntu
gutsy is running the same version (0.18). It did exibit the same error
but eventually it was fixed.
I have no knowledge to fix it, so let's wait and see.
Greetings,
Leonardo
