When using the new space-aware cleanup available in snapper 0.3.0, snapper-gui is not prepared to interpret the configuration and when trying to open the "Properties" screen there is a ValueError from python-dbus because the number of snapshots to keep in each category is expected to be a single number, not a range, and the QGROUP value is also not handled correctly and produces an error.
