From: Sergio Roa <sergio.roa <at> dfki.de> To: emacs-pretest-bug <at> gnu.org Subject: bug#2922: emacs crashes (freezes) Date: Tue, 07 Apr 2009 16:10:17 +0200
I found that the source of the problem is the lock file for Samba
directories:
A link in the client "aliena.dfki"
.#prueba.xml -> sergio <at> pandion.dfki.uni-sb.de.10144
is created and not deleted (in the server "pandion.dfki") after emacs
quit. Therefore after the second and subsequent editions of the file
emacs freezes.
