androguard 4.1.4 raises 'NoOverwriteDict object has no attribute append' in parse_v2_v3_signature when fdroidserver extracts the signer cert — this broke the self-hosted F-Droid publish from v0.4.2 on. 4.1.3 (which shipped v0.3.2–v0.4.1) parses our re-signed v1+v2-only APK cleanly; verified locally with fdroidserver.common.get_first_signer_certificate.
