This part of log-pcap.c:

   264      if (pl->filename == NULL) {
   265          SCLogDebug("Opening PCAP log file %s", pl->filename);
   266          ret = PcapLogOpenFileCtx(pl);
   267          if (ret < 0) {
   268              SCMutexUnlock(&pl->plog_lock);
   269              return TM_ECODE_FAILED;
   270          }
   271      }

does this:

t@2 (l@2) signal SEGV (no mapping at the fault address) in strlen at 0xffffffff7d93c750
0xffffffff7d93c750: strlen+0x0050:      ld       [%o2], %o1
Current function is PcapLog
  265           SCLogDebug("Opening PCAP log file %s", pl->filename);

(dbx) print *pl

I'd suggest the SCLogDebug in line 265 isn't what was meant to be there since the pl->filename tested as NULL.
