[BUG] segfault on some erroneous configurations
If captures were configured in a TCP-only listener, and
the logs were enabled, the proxy could segfault when
trying to scan the capture buffer which was NULL. Such
an erroneous configuration will not be possible anymore
soon, but let's avoid the problem for now by detecting
the NULL condition.
