Proposed as a Blocker for 32-final by Fedora user lnie using the blocker tracking app because:
This bug affects:
The installer must be able to detect (if possible) and install to supported network-attached storage devices.
Seems to be related to this change:
When iterating over the variant (list items) here:
the items get unpacked by GLib.
Maybe we need to decompose the list manually using something like GLib.Variant.get_child() before passing the items to from_structure.
Leaving the BZ to Vendy who understands the thing way better.
Fixed in a pull request: https://github.com/rhinstaller/anaconda/pull/2313
Discussed during the 2020-02-10 blocker review meeting: 
The decision to classify this bug as an AcceptedBlocker was made:
"The installer must be able to detect (if possible) and install to supported network-attached storage devices"
This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle.
Changing version to 32.
Confirmed fixed in 32.23 (in Rawhide). 32.23 wasn't built for F32, but 32.24.1 has just been built and tagged, so we should be good with tomorrow's compose.
Note that https://bugzilla.redhat.com/show_bug.cgi?id=1774746 is still happening, so iSCSI install is still broken, it's just broken a little bit further along.
