Comment 4 for bug 1241632

The upstream fix was included in ejabberd 2.1.12, and really quite small: https://github.com/processone/ejabberd/commit/2704378d43035474c5f3d8a656b81c7bc28b5ff9

If it proves too difficult to package the newer release, it should be fairly simple to apply the same fix to the 2.1.10 release.
