Re: Can't open files using ctrl+x ctrl+f

Well, I didn't have to try with -Q, emacs is working properly again.
But I still have no clue why such a thing happened.
I will try to recollect some of the things that I think I did which
could have affected its functioning:

(a)
I had added these lines to .emacs, by copying and pasting from a web
page. I checked by removing them but emacs was still misbehaving.
(setq locale-coding-system 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(prefer-coding-system 'utf-8)

(b)
Rebooting the system didn't correct it; with and without those lines
in .emacs.

(c)
I tried opening a file with a by appending a space at the end of the
file name. i.e. "c-x c-f filename ". It failed to open anything saying
the file does not exist. But just after this I tried "c-x c-f
filename" and it worked fine.

I wonder if these two events can ring a bell with anybody reading this
post. Or they may have nothing to do with my problem. Thank you for
the help.
