Yes, I do, and now I can reproduce the bug, that may be related to a
window_list applet added to a vertical panel.

I created a new user and login with him. The default desktop is shown in
the attached file Screenshot.png.

Then I modified the properties of the bottom panel:

- Orientation: left
- size: 30 pixel

Then seven gnome-terminal windows were opened and the gnome-panel become
unresponsive and start consuming 100% CPU (with Xorg), as is shown in the
attached file Screenshot-1.png.

If the size of the panel is hold at the default value of 24 pixel, then the
icons of the windows are not shown in the window_list applet (dots are
shown instead) and the bug is not triggered. So the bug may be related to
the render of the icons of windows when several windows have to be listed.
