Add iSCSI disk in installation destination

[msg...@gmail.com]

Hello,

Is it possible to add an iSCSI Target disk during Qubes OS 4.0-RC3 instalation in installation destination?
When I click on 'Add iSCSI Target...' the anaconda crashes with the same errors as here:

Is it specific to the Fedora 25 release before the fix on which the Qubes OS 4.0-RC3 is based? Or is it Qubes OS related issue? I've tried the latest Fedora 25 release and it works fine.
