(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I can reproduce this in Emacs 29.  Setting debug-on-quit and hitting
`C-g' give me the following backtrace:

Debugger entered--Lisp error: (quit)
  timer--activate([t 25385 48685 328606 nil cua--prefix-override-timeout nil nil 450000 nil] nil nil nil)
  timer-activate([t 25385 48685 328606 nil cua--prefix-override-timeout nil nil 450000 nil])
  run-at-time(0.2 nil cua--prefix-override-timeout)
  apply(run-at-time 0.2 nil cua--prefix-override-timeout nil)
  run-with-timer(0.2 nil cua--prefix-override-timeout)
  cua--prefix-override-replay(0)
  cua-copy-handler()
  funcall-interactively(cua-copy-handler)
  call-interactively(cua-copy-handler nil nil)

I'm wholly unfamiliar with cua-mode, though.  Does anybody else know
what could be happening here?
