Description of problem:


Version-Release number of selected component (if applicable):
mediawriter-4.0.7-0.fc25.x86_64

How reproducible:
2 for 2


Steps to Reproduce:
1. Write Fedora-Workstation-Live-x86_64-Rawhide-20170110.n.0.iso to a USB stick
2.
3.

Actual results:

Writes for 5-10 minutes, seems to complete, but then Error just above the progress bar; and then a dialog Authentication Required. Authenticating does nothing, the dialog spinner just spins, no error message. Esc button to back out.

Screenshot shows these things and also the journal entries at the time the error happens (was using journalctl -f during the write)

Expected results:

Should just work, not sure what's going on, this is a regression.
