This specific line is where the crash occurred? Do you still have the
core, and can you give the backtrace?

If getpwuid() were segfaulting, my guess is you would see a lot more
segfaults/aborts than in just aklog. We're not testing pwd->pw_dir for
NULL in aklog, but I'm not sure if it's possible for it to be.

You may want to continue this in a bug report (by sending something to
openafs-bugs@openafs.org), though it may not be a bug in aklog.
