unable to set executable bit on ntfs partition

Binary package hint: ntfs-3g

Not sure if this is a ntfs-3g bug or other related security package involved.

It's impossible to set the executable bit on any file on a ntfs partition mounted.

itxaka@itxaka-laptop:/media/Almacen/World of Warcraft$ ls -la Wow.exe
-rw------- 1 itxaka itxaka 7393944 2010-03-27 15:24 Wow.exe
itxaka@itxaka-laptop:/media/Almacen/World of Warcraft$ chmod +x Wow.exe
itxaka@itxaka-laptop:/media/Almacen/World of Warcraft$ ls -la Wow.exe
-rw------- 1 itxaka itxaka 7393944 2010-03-27 15:24 Wow.exe
itxaka@itxaka-laptop:/media/Almacen/World of Warcraft$ sudo chmod +x Wow.exe
[sudo] password for itxaka:
itxaka@itxaka-laptop:/media/Almacen/World of Warcraft$ ls -la Wow.exe
-rw------- 1 itxaka itxaka 7393944 2010-03-27 15:24 Wow.exe
itxaka@itxaka-laptop:/media/Almacen/World of Warcraft$

Copying the file to my home directory and setting it executable works with no problems.

itxaka@itxaka-laptop:~$ ls -la Wow.exe
-rwx--x--x 1 itxaka itxaka 7393944 2010-06-24 11:28 Wow.exe

Trying to make it executable via Nautilus doesn't work either.
