This does not *necessarily* indicate a bug in libdbus-1-3; it *might*
be a bug in libdbus-1-3, but it could equally well be gvfsd-dnssd (or
some other library used by gvfsd-dnssd) passing an invalid pointer to a
function in libdbus-1-3. I would guess it's most likely to be something
to do with Avahi.

It's often better to report crashes as a bug in whatever program
is crashing, in this case gvfsd-dnssd in the gvfs-backends package,
and let the maintainer of that component reassign it if appropriate:
that gives us more information about the packages and dependencies
involved. Please send the output of "reportbug --template gvfs-backends"
to this bug address to confirm what the versions of its dependencies are.

If this crash does not happen again, there is probably nothing we can
do about it: there isn't really enough information in this crash report
to know where the bug is, much less to fix it.

If it happens repeatedly, installing the systemd-coredump package is the
easiest way to get more information about a crash in a background program.
Please see <https://wiki.debian.org/HowToGetABacktrace#Core_dump> for
more details.
