This has been an interesting morning.. At first I couldn't, but I was
starting hipd through sudo which seems (?) to supress those. Now,
running hipd on my laptop logged in as as su (not through sudo) I get it
here also. So yes, I'm able to repeat it on any machine I try it on.
Here's a gdb trace:

Title:
Minor segfault on failed startup
Status in Host Identity Protocol for Linux:
New
Bug description:
If the kernel module checks during startup fails, hipd segfaults
instead of exiting nicely. This because the hip_xfrmapi_nl_ipsec
(lib/tool/xfrmapi.c:49) hasn't been initialized before it is used in
hip_delete_hit_sp_pair() [which is called on exit].
quick & dirty patch attached
