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@gnu.org mailing list.

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

I use iswitchb and the virtual buffer feature
(iswitchb-use-virtual-buffers set to t).  It's a great feature, but it
doesn't play well with symlinks.

I keep all my config files in a git repository.  For example, my
~/.emacs is a symlink to ~/repos/configs/dot-emacs.el.  Now I fire up
iswithb and type ".emacs".  There's no such buffer, so it shows the
virtual buffer ".emacs" and I hit RET.

Now I'm queried:

  Symbolic link to Git-controlled source file; follow link? (y or n) 

That's ok, and I say yes.  The echo area says:

  Followed link to /home/horn/repos/configs/dot-emacs.el

Also, the file is opened, and a buffer dot-emacs.el exists now.  But
then I get another query:

  No buffer matching `.emacs', create one? (y or n) 

When I say yes, an empty .emacs buffer is created.  When I say no, no
new buffer is created, but I stay in the buffer I invoked iswitchb
from.  The dot-emacs.el buffer is open, but not switched to.

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/share/emacs/23.1.50/etc/DEBUG for instructions.

Yep, you send a mail to <bugnumber>-done@emacsbugs.donarmstrong.com.
That's what I did, so now it's closed.
