It's better than nothing.  I want to know if this problem happens because of
recent changes in various posn-* functions.  It will help me identify the
culprit if there is one (as opposed to if this is an old problem that no one
bothered to report).

Too bad.  I'd like to have a way of reproducing this here, because I have
difficulty understanding the data and backtraces you posted.  Specifically,
I don't understand which code signals an error, what data triggers that, and
how the data which triggers the error is related to the switch-frame event
in the first place.

The "C-h k" case should be already fixed (by "other means"), so it cannot
help me anymore.  In any case, these two cases only share one thing in
common: that the switch-frame event was delivered to functions that didn't
expect it.  Everything else is different.

So if you cannot reproduce the org-capture case in "emacs -Q", perhaps some
other recipe which causes the same backtrace can be reproduced?

Thanks.
