Thanks, Anselm.
It actually happens with *all* windows.

Output from xprop for a couple of examples:
1. Iceweasel
------------
(only meaningful lines)
WM_STATE(WM_STATE): window state: Normal
                        icon window: 0x0
WM_HINTS(WM_HINTS):
                        Client accepts input or input focus: True
                        Initial state is Normal State.
WM_WINDOW_ROLE(STRING)="browser"
WM_CLASS(STRING) = "Navigator", "Iceweasel"
WM_NAME(STRING) = "suckless.org software that sucks less - Vimperator"

2. Terminal - I use sakura
--------------------------
_NET_WM_USER_TIME(CARDINAL) = 10685704
WM_STATE(WM_STATE):
                        window state: Normal
                        icon window: 0x0
WM_HINTS(WM_HINTS):
                Client accepts input or input focus: True
                Initial state is Normal State.
                window id # of group leader: 0xa00001
XdndAware(ATOM) = BITMAP
_MOTIF_DRAG_RECEIVER_INFO(_MOTIF_DRAG_RECEIVER_INFO) = 0x6c, 0x0, 0x5, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0,0x0, 0x0, 0x0, 0x10, 0x0, 0x0, 0x0
_NET_WM_SYNC_REQUEST_COUNTER(CARDINAL) = 10485766
_NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_NORMAL
_NET_WM_USER_TIME_WINDOW(WINDOW): window id # 0xa00005
WM_CLIENT_LEADER(WINDOW): window id # 0xa00001
_NET_WM_PID(CARDINAL) = 11469
WM_LOCALE_NAME(STRING) = "eo.UTF-8"
WM_CLIENT_MACHINE(STRING) = "inti.casa.org"
WM_NORMAL_HINTS(WM_SIZE_HINTS):
                program specified minimum size: 11 by 20
                program specified resize increment: 9 by 18
                program specified base size: 2 by 2
                window gravity: NorthWest
WM_PROTOCOLS(ATOM): protocols WM_DELETE_WINDOW, WM_TAKE_FOCUS, _NET_WM_PING, _NET_WM_SYNC_REQUEST
WM_CLASS(STRING) = "sakura", "Sakura"
WM_ICON_NAME(STRING) = "sakura"
_NET_WM_ICON_NAME(UTF8_STRING) = 0x73, 0x61, 0x6b, 0x75, 0x72, 0x61
WM_NAME(STRING) = "sakura"
_NET_WM_NAME(UTF8_STRING) = 0x73, 0x61, 0x6b, 0x75, 0x72, 0x61


The WM_CLASS and WM_NAME all look very sensible.

What do you reckon?
