For the oldstable distribution (lenny), this problem has been fixed in version 2.0.1-6+lenny3. For the stable distribution (squeeze), this problem has been fixed in version 2.1.5-3+squeeze1. For the testing distribution (wheezy), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 2.1.6-2.1. We recommend that you upgrade your ejabberd packages.
