**Short description of error**
When I try to add an "Image Sequence" node to an already created and opened node group in Blender´s Compositor I receive a traceback error message with a failure in line 3066. I made sure that the folders/files have NO special characters or something in it! I googled my problem before, but I wasn´t able to find another post like this, so I decided to bring it over here.
//Traceback (most recent call last):
File "C:\Program Files (x86)\Blender Foundation\blender-2.78-windows64\2.78\scripts\addons\node_wrangler.py", line 3066, in execute
node.image = img
AttributeError: 'CompositorNodeGroup' object has no attribute 'image'
location: <unknown location>:-1"//
**Exact steps for others to reproduce the error**
-Open up Blender (Cycles)
-Go to the Compositor
-Create any node group; in my case it was a "Color Mix" node, and the group was connected to another node
-Switch to the node group (tab in)
-Try to add an image sequence (Add, Input, Image Sequence). I used a sequence of 150 images (30 fps).
