I'm using python-blivet-1.12.8 with blivet-gui 1.0.5 on Fedora 23. I have a btrfs volume on an LVM logical volume. After launching blivet-gui, if I click on the btrfs volume name listed under "Btrfs Volumes" on the left side of the blivet-gui window, an error dialog which states "An unknown error has occurred" is displayed and the Physical View for the btrfs volume is not updated.


Here is the first section of the exception report:
