librepo in ubi8-minimal breaks "microdnf install --nodocs"

[rolweber]

In ubi8-minimal:latest, calling microdnf install --nodocs fails with status 141. In ubi8-minimal:8.0, it worked. I could reproduce this problem by upgrading only librepo in the 8.0 images.

Dockerfile:

FROM registry.access.redhat.com/ubi8/ubi-minimal:8.0

RUN microdnf update \
    librepo \
 && rm -rf /var/cache/yum

RUN microdnf install --nodocs bzip2

output (redacted):
