For the oldstable distribution (wheezy), this problem has been fixed in version 1.3.0-2+deb7u1.

For the stable distribution (jessie), this problem has been fixed in version 1.4.1-2+deb8u1.

For the testing (stretch) and unstable (sid) distributions, this problem has been fixed in version 1.4.4-1.

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