I know, I read the thread before I made the recent changes. (c:

It was just a precaution.  Mode hooks should be run as late as
possible.  Otherwise this might defeat their purpose of providing a
means for the user to override values set by the mode.
`TeX-set-mode-name' has to be run after those hooks, however, because
they may activate minor modes which have to be indicated by the mode

Pff, waste of space. (c;

In my case it wasn't.  I started Emacs with the tool bar disabled,
loaded a LaTeX file and typed `M-x tool-bar-mode RET'.  Then the LaTeX
tool bar appeared.  But when I loaded a new LaTeX file after that I
got a regular tool bar.  I guess `LaTeX-maybe-install-toolbar' was
only run once when the tool bar was activated while it has to be run
every time LaTeX mode is being activated.
