bug#12824: 24.2.50; Strange default string brought by M-n after `C-x C-v'

[Dani Moncayo]

Recipe from "emacs -Q":

C-x b h i <RET> / * h e l l o C-x C-v M-n

I observe that `M-n' writes in the minibuffer a default argument "c:/*hello".

If I repeat the experiment changing "/*hello" with, for example,
"hello" or "/*hello/", no default argument is brought by `M-n'.

Is this a bug no? If not, what is the rule here for getting a default argument?

TIA.
