sudo crashes on wrong access rights in /etc/suduers.d/x on 10.04

[Dominik Holler]

On an up to date ubutnu 10.04 sudo crashed always, if there was a file with access rights 0644 in /etc/sudoers.d/ .
Changing the access rights of the file to 0440 makes sudo useable again.
Does this affect only me?

sudo is version 1.7.2p1-1ubuntu5.4
