I managed to somewhat isolate the bug even further:
(let* ((directory (string-append (canonicalize-path directory) "/"))
(dot-git (repository-discover directory)) ; <- here
(repository (repository-open dot-git))
(workdir (repository-working-directory repository))
(head (repository-head repository))
(oid (reference-target head))
(commit (commit-lookup repository oid))
(tree (commit-tree commit))
(files (tree-list tree)))
repository-discover is an FFI call into libgit2, that appears to be
segfaulting while… trying to prettify some filename? At least that's
what "git_path_prettify", which lies on the call trace sounds like.
