Yep, that was easy to reproduce. I've hopefully fixed that in my last
commit. The style hook application in `TeX-run-style-hooks' is now
guarded by a `condition-case' that simply ignores void-function errors.

The result is that (1) you obviously don't get an error when opening the
sample file again, and (2) the auto file has the contents
--8<---------------cut here---------------start------------->8---
(TeX-add-style-hook
"unit"
(lambda ()
(TeX-run-style-hooks
"latex2e"
""
"article"
"art10")))

afterwards, i.e., the problematic code is gone. Basically, everything
is gone. What's there is the result of reparsing.
Bye,
