[lttng-dev] Add pid context to UST events

I tried to add pid context to UST events to distinguish events from
multiple processes. I do have this error:

$ lttng create bidon
Session bidon created.
Traces will be written in /home/francis/lttng-traces/bidon-20120601-142031

$ lttng enable-event -a -u
All UST events are enabled in channel channel0

$ lttng add-context -u -t pid
Error: pid: UST invalid context
Warning: Some command(s) went wrong

Am I doing something wrong?
