[sr-dev] segfault calling tls.list in sercmd

Dear sirs, I'm not sure where should I report a backtrace for this event; so let me add some details in the mailing list, but please advice me if there were more appropriate places for this. Moreover, I'm not sure if it is actually a bug in libssl. In this case, I just wanted you to know it.
