In f15 the gnome and xfce window managers both seem to set a window manager hint
that includes the process ID so you can probably get this by running xwininfo
and clicking the suspect window:
$ xwininfo -wm
xwininfo: Please select the window about which you
would like information by clicking the
mouse in that window.
xwininfo: Window id: 0x2200005 "bmr@bmr:~"
Window manager hints:
Client accepts input or input focus: Yes
Initial state is Normal State
Displayed on desktop 0
Window type:
Normal
Process id: 2157 on host bmr.fab.redhat.com
Frame extents: 1, 1, 28, 2
$ pga 2157
2157 ? Sl 0:05 gnome-terminal
24640 pts/0 S+ 0:00 grep --color=auto 2157

Tim, Patrick, Bryn - thanks for valuable tips. xwininfo and xprop
are both capable return PID and hostname of window controlling process,
which is all I need.
Btw, my cryptic process was LXDA Policykit Authentication Agent
(/usr/libexec/lxpolkit). I not know why it is launched from XFCE session,
maybe some relict from my previous experiments when I was searching some
replacement for Gnome 2.x.
Fortunately, this applet is well described in XFCE Preferences menu
(in contrast with crippled ones as "load color profiles", "unlock
certificates" and other weird named applets, for which is problem
locate destination file), thus wasn't problem disable it.
