n/a

Affected TemplateVMs (e.g., fedora-23, if applicable):

Steps to reproduce the behavior:

Click "Yes" for "Owner: Qubes Master Signing Key key does not exist."

Expected behavior:

See a dialogue box with
"Owner: Marek Marczykowski-Grecki (Qubes OS signing key) <..> key does not exist."

Actual behavior:

Python Traceback:

dialog.PythonDialogErrorBeforeExecInChildProcess

General notes:

I tried this in a fedora 26 docker container (github.com/freddierice/dockerfile-qubes-builder).

The error has to do with a unicode character being converted to ascii from the arglist during an os.exec call.
