No; it is a different problem altogether...

  ... I've tried with this change, but it isn't the cause
of the problem. The coding should never get as far
as calling any of these  \@calc at ....  internals.

It is failing while  natbib  is parsing the info it needs
in deciding what kind of citation it is going to display.
The lack of robustness of an  APAcite  macro causes
premature expansions, ultimately leading to the crash.

Indeed, it encounters all sorts of assignments while
simply expanding macros for pattern-matching.
So something has to go wrong eventually, and its
\@calc at post@scan  that first throws up an error message.

Nice thought, that maybe fixing one error might also
prevent others --- just not this time.
