and the precise symptoms of the bug:

I am getting the following error all the time. The steps to reproduce
this bug is as follows:

     i.   using putty in WinXP to ssh to Fedora GNU/Linux
     ii.  run emacs in it
     iii. enable xterm-mouse-mode and mouse-wheel-mode
     iv.  use the mouse to scroll down in putty
