I built xemacs-21.2.27 an played a little with it and it's tabs. And it
crashed. It might be interesting - short before a crash I invoked wininfo and
it gave the following:

Fatal error (11).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
If you have access to the PROBLEMS file that came with your
version of XEmacs, please check to see if your crash is described
there, as there may be a workaround available.
Otherwise, please report this bug by running the send-pr
script included with XEmacs, or selecting `Send Bug Report'
from the help menu.
As a last resort send ordinary email to `crashes(a)xemacs.org'.
*MAKE SURE* to include the information in the command
M-x describe-installation.
If at all possible, *please* try to obtain a C stack backtrace;
it will help us immensely in determining what went wrong.
To do this, locate the core file that was produced as a result
of this crash (it's usually called `core' and is located in the
directory in which you started the editor, or maybe in your home
directory), and type
gdb /usr/local/bin/xemacs core
then type `where' when the debugger prompt comes up.
(If you don't have GDB on your system, you might have DBX,
or XDB, or SDB. A similar procedure should work for all of
these. Ask your system administrator if you need more help.)
Lisp backtrace follows:

This is the same crash Ray is seeing. Please try the attached patch (Ray is
testing it too) to see if it fixes things. I am going to commit this very
soon unless it becomes clear that it does not solve the problem.

New subject: Tabs [was Crash report]
I applied your patch and now XEmacs seems to be stable for longer time. At
least, I've been doing my work for several hours without crashes.

But I ran across some strange behavior of gutters, which is described by this
test case:
-------------------------------------------------------------------------------
(progn (custom-set-variables '(gutter-visible-p nil))
(let ((buf (generate-new-buffer "Test")))
(switch-to-buffer buf)
(insert "Where is " (buffer-name buf) " in tabs?"))
(custom-set-variables '(gutter-visible-p t)))
-------------------------------------------------------------------------------
Let's suppose this test case is stored in test.el and do the following:
hookah : npakoulin >$ xemacs -vanilla -l test.el &
What we get is
but should be (as I see it)

* gutter-items.el (gutter-visible-p): Mkae sure the gutter gets
updated when it becomes visible.
