I confirmed it on WindowsXP SP3, Japanese locale.
I got the messege at:
Freeciv-2.4.0-beta1-win32-gtk2, Freeciv-2.4.3-win32-gtk2, Freeciv-2.5.0-beta1-win32-gtk2, Freeciv-2.5.0-beta0-r25500-win32-gtk3
I didn't get the message at:
Freeciv-2.3.4-win32-gtk2, Freeciv-2.3.5-win32-gtk2
And I don't get the message at Freeciv-2.4.3-win32-gtk2 if I set LANG to en locale before I start up freeciv.
I think the problem occurred in non-English freeciv 2.4+ and Windows XP system.
for example, German - Windows XP
