Try M-x report-emacs-bug.  Maybe this can fail more gracefully.

You can probably try and fool hs-minor-mode by adding dummy matching chars
(typically wrapped in some ad-hoc command, such as \ignore{[} where \ignore
is defined as a nop that takes an arg and throws it away).
Kind of ugly, tho.  Sadly, LaTeX is inherently non-structured, although it
happens to be properly structured in 99% of the cases.

You may want to try outline-minor-mode for that.
