Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

* I started Emacs in a git working tree, whose checked-out branch was
  named "master":

    $ cd /usr/local/src/emacs-via-git/src
    $ git branch
    * master
    $ ./emacs -Q -nw

* I ran vc-dir by typing C-x v d, and noticed that the output was
  correct: in particular, it said "Branch : master"

* I created, and switched to, a new branch, by typing 

    M-! git checkout -b fred RET

* I "refreshed" the *vc-dir* buffer by typing g ("revert-buffer").  I
  noticed that it _still_ said "Branch : master".  This is the bug; I
  expected to see "Branch : fred".

* I killed the *vc-dir* buffer with C-x k RET, then recreated it with
  C-x v d.  This time, I saw "Branch : fred", as I expected.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/src/emacs-via-git/etc/DEBUG for instructions.

`vc-dir-refresh' needs to recompute the header for vc-ewoc (i.e. run
(vc-dir-headers vc-dir-backend default-directory) )
and put the result back in the ewoc.

Do you want to take a stab at it?
