Description

When starting an UST trace in a small C application, when we call 'lttng_start_tracing' the error "No kernel consumer detected" is thrown (minimal.c:145).
This problem disappear if, during the lttng-sessiond run, a kernel trace was made previously.

The files that are joined to this bug report allows to reproduce the error.
It seems that the bug is located between commits b883c01 and e371dbd.
