We are extensive consumers of this library and besides the issue reported in #323, we have seen an increase of empty git-upload-pack given errors reported by our users since we upgraded from v5.3.0 to v5.4.x.

The error seems unrelated to the Git v2 protocol as reported in #64 or #157, given users that previously were able to perform operations on their e.g. GitHub repository using v5.3.0 are now no longer able to do so using v5.4.x.

Diving into the changelog nothing directly related seems to have changed, except for some plumbing changes in #246.
