Blender 2.8 crashes when working with colliders

[chrbaumeister]

When adding a collider I get a traceback error. When starting continous update after it Blender crashes.

Traceback (most recent call last):
  File "C:\Users\...\AppData\Roaming\Blender Foundation\Blender\2.80\scripts\addons\Modeling-Cloth-2_8-master\ModelingCloth28.py", line 2092, in collision_object_update
    if 'colliders' in extra_data:
NameError: name 'extra_data' is not defined
File "C:\Users\...\AppData\Roaming\Blender Foundation\Blender\2.80\scripts\addons\Modeling-Cloth-2_8-master\ModelingCloth28.py", line 2087, in collision_object_update

Update:
Even tried it with the latest Build (749d53effd58, Win 64 bit) and reinstalling the add on.
