Indeed, same for me.

Hehe, I'd say that's pretty consequent to augment a separator with the
text "separator". :-)

Much better.

I think it is not our business to set `tool-bar-style' explicitly but
rather the user should do that based on his or her preferences.

Here, the value is nil which, according to its docstring, should mean
"use the system default or image if no system default".  So I guess
there's also some GTK setting which a user could configure, and then
Emacs/AUCTeX should follow suite.
