bro segfaults on startup

What happens if you run it by hand inside gdb?

(Also, FWIW, I were to make a wild guess, it would be that this relates
to permissions for reading the packet filter.)

Which packet filter do you mean?

Scott Campbell mentioned it may be a problem with the resolver library, as others have had similar problems in the past.

Here is the output from strace, ltrace, gdb, ldd, and version information for suspect libraries:

Summary : The GNU libc libraries.
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.
