qubes-vm-settings error

[seshu]

I recently updated dom0, after the xen vulnerabilities were identified, and I"m coming across this error when I try to open Qubes Setting for any VM.

TypeError: 'NoneType' object is not subscriptable at line 9 of file /usr/bin/qubes-vm-settings.

The Details are:

Anyone else come across this? Any solution? I'm running 4.0.1

Thanks in advance.

Hi, after the recent update, I'm not getting the same error message as before, but I'm still unable to view my Qubes Settings from Qubes Manager. Now I'm getting a

AttributeError: 'VMSettingsWindow' object has no attribute 'dev_list' at line 9

Checking to see if anyone knows of this problem? Thanks!
