OK. If I take out the bits from users.py:
import libuser
class Users:
    def __init__ (self):
        self.admin = libuser.admin()
    def setRootPassword(self, password):
        rootUser = self.admin.lookupUserByName("root")
        self.admin.setpassUser(rootUser, password, True)
        self.admin.modifyUser(rootUser)
u = Users()
u.setRootPassword('adsf');

I can reproduce the problem and strace it (only relevant parts):

open("/etc/passwd", O_RDONLY)           = 5
write(5, NULL, 0)                       = -1 EBADF (Bad file descriptor)
fcntl(5, F_SETLK, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}) = 0
--
open("/etc/passwd", O_RDONLY)           = 5
write(5, NULL, 0)                       = -1 EBADF (Bad file descriptor)
fcntl(5, F_SETLK, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}) = 0


Duh? Why does it open with O_RDONLY and then tries to *write*!? Do I
miss something?
