Subject: bug#4527: Emacs removes Extended Attributes when saving

From: David Euresti <[email-masked]>

When I edit a file that contains xattrs the xattrs are removed when I
save the file inside of emacs.

Example:
$ touch a.txt
$ xattr a.txt user.foo bar
$ xattr -l a.txt
user.foo: bar
$ emacs a.txt
add a line C-x C-s
$ xattr -l a.txt

You can get the xattr tool from
http://pypi.python.org/packages/source/x/xattr/xattr-0.4.tar.gz

Thanks,
David

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/22.2/etc/DEBUG for instructions.
