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 bug-gnu-emacs@gnu.org mailing list, and to the gnu.emacs.bug news group. Please describe exactly what actions triggered the bug and the precise symptoms of the bug: ###################################################################### Consider the attached .emacs in an otherwise empty home directory. Edit files of the same name residing in different directories. For example: c:\emacs-22.2\bin\runemacs.exe c:\test\a\jack.txt c:\test\b\jack.txt M-x list-buffers RET . jack.txt\b 0 Text c:/test/b/jack.txt jack.txt\a 0 Text c:/test/a/jack.txt *scratch* 0 Lisp Interaction * *Messages* 243 Fundamental C-x C-c The resulting .emacs.desktop is attached. Restart emacs like this: c:\emacs-22.2\bin\runemacs.exe M-x list-buffers . jack.txt\b 0 Text c:/test/b/jack.txt jack.txt 0 Text c:/test/a/jack.txt *scratch* 0 Lisp Interaction * *Messages* 280 Fundamental Note the different naming of file c:/test/a/jack.txt. If you edit more than two files of the same name every other buffer is named the conventional way like jack.txt<2> and so on. ######################################################################
