software-properties-gtk broken after last update

Software & updates doesn't start after update from 0.96.24.32.14 to 0.96.24.32.18. Python throws an error:

Traceback (most recent call last):
File "/usr/bin/software-properties-gtk", line 100, in
app = SoftwarePropertiesGtk(datadir=options.data_dir, options=options, file=file)
File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 165, in __init__
self.info_bar_ubuntu_pro.set_visible(self.sp_settings.get_boolean("ubuntu-pro-banner-visible"))
AttributeError: 'SoftwarePropertiesGtk' object has no attribute 'info_bar_ubuntu_pro'

It doesn't touch software-properties-kde which has been upgraded too.
