Did you check the other functions? (If not, before you do, see below.)

Sorry, i was not clear. I would use ‘message’ in several places, each
w/ a unique format string (to avoid Emacs combining them in *Messages*),
to trace the execution path. That would help answer some aux questions:
Did the function finish? Did it return the form as expected?
I tried that, and message always said I'm in the buffer I was
supposed to be in, even though the next message was the error.
To be super-safe I added
(assert (eq major-mode 'clojure-mode))
before every single form of my function! Right now, I only have one
clojure-mode buffer open. The original post-command-hook error still
occurs, but the assertions are always true anyhow. So it doesn't
seem to be caused by being in the wrong buffer...
With the series-of-‘message’ calls "instrumentation", i would expand the
set of interesting state to check other assumptions. I see several vars
that are ‘let’-bound in minibuffer.el that are good candidates.
Sort of in parallel (maybe you found a bug in Emacs!), i would also try
a trivial func that does no computation and returns constant, known
data, likewise "instrumented", to validate the completion machinery.
Did you already do that?
