alias ls='ls --color=auto' causes /bin/ls segfaults in some directories.

Egg:

$ pwd
/var/abs/local
$ ls
Segmentation fault
$ cd ..
$ ls
PKGBUILD.proto devel kernels network x11
base editors lib office x11-drivers
community extra local system x11-libs
daemons install.proto multimedia unstable
$ cd ..
$ ls
abs cache db ftp local log ntop run spool tmp
backup chroot empty lib lock mail opt service state www
$ cd ..
$ ls
Segmentation fault
$ pwd
/
$ alias ls
alias ls='ls --color=auto'
$ unalias ls
$ ls
bin dev home lib64 mnt proc sbin tmp var
boot etc lib lost+found opt root sys usr
$

Both i686 and x86_64 systems affected.

Temperary solution: unalias ls, comment this alias in .bashrc's
