23.0.60; emacs hangs when using (tabbar-forward-group) repeatly.

23.0.60; emacs hangs when using (tabbar-forward-group) repeatly.

[Kyle M. Lee]

I compiled cvs emacs with mingw32-gcc3.4 and image support on Windows
XP, and ran with --disable-font-backend.

To reproduce this bug, keep pressing key-binding to
(tabbar-forward-group), and emacs will hang, even I release all the
keys pressed. That looks like emacs keep refreshing the tabbar's
arrow.

I cannot reproduce this on GNU Emacs 23.0.60.1 (i686-pc-linux-gnu, GTK+
Version 2.12.0) of 2008-03-13 on escher.  Since tabbar.el is not part of
Emacs, you need to make sure the bug isn't in tabbar.el, even though it
may not happen in earlier versions of Emacs.  What version of tabbar.el
are you using?  (I tested with tabbar.el,v 1.69 2006/06/08 08:27:39.)

I found a simplest way to reproduce this bug on Windows XP.
C-h t RET to open tutorial(chinese language), and keep pressing C-~
which is the key-binding to (tabbar-forward-group) several times,
then the emacs hanged.

Maybe this bug is related to unicode something? I know little about
emacs internal.
