TIL. I didn't even know that git-show-branch(1) is a thing.

By default, no refs but "HEAD" and refs starting with "refs/heads/*"
have a reflog. Thus, your ref "refs/pullreqs/1" won't have a reflog, and
git-show-branch(1) then happily segfaults when it didn't find a reflog
at all. This is of course a bug that needs fixing.

I'll send a patch in a bit, thanks for your report!

Patrick
