For the stable distribution (lenny), this problem has been fixed in version 1.3.1-17lenny4.

For the oldstable distribution (etch), this problem has been fixed in version 1.3.0-19etch3.

Binaries for the amd64 architecture will be released once they are available.

For the testing distribution (squeeze) and the unstable distribution (sid), this problem has been fixed in version 1.3.2a-2.
