For the stable distribution (lenny), this problem has been fixed in version 2.0.1+dfsg1-2.3+lenny0.

Due to a technical limitation in the Debian archive management scripts the update for the old stable distribution (etch) cannot be released synchronously. It will be fixed in version 2.0.1+dfsg1-1.2+etch0 soon.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your python-crypto package.");
