Yes, in any buffer or new file and buffer. It happened twice in last
days, and I know that I was editing with Wdired so much.

That I cannot know, I would solve it if I would know it.

I am always using Emacs and I never got this problem before, I would
otherwise report it, right? No need to stop using Wdired to find out
if it happens, as that has been determined that it does not happen by
my previous historical usage of Emacs.

I cannot say what invokes it, I just know that I am using a lot C-x
C-q and C-c C-c and also "q" to exit Dired buffer and a lot of "^" to
go to upper directory. And just by my changed usage of Emacs in last
few days where I am editing a lot of file names and directories, I can
estimate that it relates to Wdired or Dired. And I do a lot of
searches one after the other.
