I rebuilt Emacs 23, both LUCID and GTK.  But I have no such a
problem as before.  Tools (including Gcc) and libraries I use
are all Fedora Core's.  The configure options are:

LUCID: --verbose --enable-font-backend --with-freetype --with-xft\
 --without-xim\
GTK: --verbose --enable-font-backend --with-freetype --with-xft\
 --with-gtk --without-xim

Well, how about setting `w3m-track-mouse' to nil and restarting
emacs-w3m?  ("restarting" means to kill all the emacs-w3m buffers
using the Q command and to start it again.)  The nil value for
`w3m-track-mouse' disables displaying of the balloon help.  I
guess the problem might arise if something lacks in your system
to display the balloon help.  For example, there's no font for
the balloon.  I don't know how to fix it even if it is bingo,
though.

This also might do the trick:

(remove-hook 'w3m-after-cursor-move-hook 'w3m-print-this-url)

or

(setq w3m-after-cursor-move-hook nil)

I found no oddity there.
