Fwd: [qubes-users] Error using Qubes Manager backup/restore after migrating to 3.0-RC1

Hi - I sent this to the qubes-users list, but I think it is more
appropriate for qubes-devel.

Hi all,

I encountered an error while trying to restore my appvms after migrating
to 3.0-RC1. After selecting my backup file and entering my
decryption/verification password, I get an error from Qubes Manager :

Whoops. A critical error has occured. This is most likely a bug in Qubes
Manager.

AttributeError: 'NoneType' object has no attribute 'endswith'
at line 220
of file /usr/lib64/python2.7/site-packages/qubesmanager/restore.py.


In the "Show Details" I have:

I started following the manual rescue procedure described here:
https://www.qubes-os.org/doc/BackupEmergencyRestoreV3/

I verified the integrity of the backup-header. Then I noticed that the
time names of the archive seem a bit off. Some read like this:

vm38/private.img.000
vm38/private.img.000.hmac
vm38/icon.png.000
vm38/icon.png.000.hmac
vm38/apps.templates.000
vm38/apps.templates.000.hmac
vm38/root.img.000
vm38/root.img.000.hmac
vm38/root.img.001
vm38/root.img.001.hmac


But others read like this:

vm25/..000
vm25/..000.hmac
vm25/..001
vm25/..001.hmac
vm25/..002
vm25/..002.hmac
vm25/..003
vm25/..003.hmac
vm25/..004
vm25/..004.hmac

Could this be causing the error?
