so, I think there is an infinite loop generated between yas--auto-fill and orgalist--auto-fill:
--------------
Debugger entered--Lisp error: (error "Lisp nesting exceeds ‘max-lisp-eval-depth’")
current-left-margin()
move-to-left-margin()
forward-paragraph()
yas--auto-fill()
orgalist--auto-fill(yas--auto-fill)
apply(orgalist--auto-fill yas--auto-fill nil)
#f(advice-wrapper :around yas--auto-fill orgalist--auto-fill)()
yas--auto-fill()
orgalist--auto-fill(yas--auto-fill)
apply(orgalist--auto-fill yas--auto-fill nil)
#f(advice-wrapper :around yas--auto-fill orgalist--auto-fill)()
yas--auto-fill()
orgalist--auto-fill(yas--auto-fill)
apply(orgalist--auto-fill yas--auto-fill nil)
#f(advice-wrapper :around yas--auto-fill orgalist--auto-fill)()
yas--auto-fill()
-----------------------
the workaround is to disable yas-global-mode, which I should have done anyway. But this might be something to figure out how to manage in any case -- do you htink this counts ass a yasnippet issue or an orgalist issue or a message-mode issue?
