Re: problems to use lttng

Hi Rilson,

Sorry about that, I am currently in the middle of a major rework of the
serialization mechanism, so I cannot easily post a fix for this version.
You may want to find the version of LTTng just before the "compact"
facility addition in the compatibility list, and use the compatible
ltt-control and LTTV versions.

Sorry about this, it should be fixed in a week or so with the new
release.
