emerge --info bustle libpcap
dev-util/bustle is crashing with libpcap-1.8.1 as it has some problems with oversized d-bus packages.
There are some workarounds implemented in libpcap-upstream  and the developer of bustle suggests  to backport these to the current package.
 https://github.com/wjt/bustle/commit/f62cf6bfa662af4ae39effbbd4891bc619e3b4e9 and https://bugs.freedesktop.org/show_bug.cgi?id=100220
Should be fixed in modern bustle-0.8.0
