That means it's almost certainly a libpcap bug, not a tcpdump or Wireshark bug.

That is the following libpcap bug:
http://sourceforge.net/tracker/?func=detail&atid=469577&aid=3554749&group_id=53067
That bug says:
> Running tcpdump on a host without a mounted usbfs will result in a segfault, unless the interface is specified.
>
> The return value of libusb_init() [1] should be checked to make sure it's appropriate to continue with the other calls to libusb.
and the reported stack trace:
http://pastie.org/4392531
is, starting with pcap_findalldevs(), the same.
I.e., it's a libpcap bug, not a Wireshark bug. Closing. I'll fix the libpcap
bug when I get the chance; I'll ask Michael Richardson to put out a libpcap
1.3.1 release, for various upstream Linux distributions to pick up (or they can
just pick it up themselves from Git). ("INVALID" should really be, as a
certain purple-anteater-themed bug system would call it, "3rd party to
resolve", the "3rd party" here being tcpdump.org, but there's no such
resolution in the Wireshark Bugzilla. I think some other Bugzillas may have
that.)
