bug#49675: 28.0.50; minibuffer-quit produces error

[Pankaj Jangid]

Note: this error does not occur with default configuration i.e. with
‘emacs -Q’. But this was not happening before the recent minibuffer
changes. So I’ll try to isolate the cause. Here is a dump:

‘minibuffer-quit’ produces this (or similar) error whenever I change my
mind and press ‘C-g’ before entering any text into the minibuffer
prompt. I have tried this at a couple of places. Simplest is this
one. Press ‘M-x’ and then press ‘C-g’ without entering any text on the
minibuffer prompt.
