Packages in the oldstable distribution (lenny) are not affected by this problem.

For the stable distribution (squeeze), this problem has been fixed in version 1:4.1.4.2+svn3283-2+squeeze1.

For the testing (wheezy) and unstable (sid) distributions, this problem will be fixed soon.

We recommend that you upgrade your shadow packages.");
