Comment 1 Matej Stuchlik 2015-04-15 16:11:24 UTC

The issue here is that we replace a directory with a link during an update which RPM/cpio doesn't handle well, apparently. The links are there because python-requests bundles python-urllib3 and python-chardet, which are deleted during build and replaced with links to the respective system modules.

This also means this bug does not trigger when the packages is either installed anew, or when it is updated from python-requests 1.1.0 (this version does not ship the bundled modules).
