* What version of the product are you using? On what operating system?

I'm using the latest SVN version.
With Debian testing. kernel version is 3.2.0

* Please provide any additional information below.

I've made a patch to fix this problem. It is because we should use 
dst_metric_raw() instead of dst_metric().
