Dunno whether this will help.  No, I cannot keep the session open until
I hear back from you.  I opened gdb and hit `bt' to get a backtrace.  I tried to
print the selected_window at the point where it seemed like perhaps it was
trying to get the buffer of a window (?).

Probably the info here won't tell you enough, but I don't know what commands to
use to get you the info you might need.
Anyway, here is the backtrace from gdb.  The Lisp function
`old-read-from-minibuffer' is just a `defalias' at startup to
the built-in C function `read-from-minibuffer', as follows:
(unless (fboundp 'old-read-from-minibuffer)
  (defalias 'old-read-from-minibuffer (symbol-function 'read-from-minibuffer)))
