In this BZ:

https://bugzilla.redhat.com/show_bug.cgi?id=473794

there is a discussion of F10 client that needed a fix.
The common things between BZ and your problem is the same error msg and
the same F10 client.

So, trying from higher F? client should confirm the presence of a fix and
what you need to do next.

In case upgrading the client does not help, the BZ also shows how to capture
a relevant traffic in order to file your own BZ report.
