Hi,

This appears to be a duplicate of Launchpad bug 961482 [1] and upstream
bug 42979 [2]. The issue is actively being investigated and worked on
upstream [3]. We'll actively be tracking this issue and pull in a fix
when it is available. Thanks for your patience. Please continue to
track either the Launchpad bug or the upstream bug/thread for additional
information.

Thanks,
Leann
