Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: Kubuntu 18.04.1
Graphics card: RX 480 8gb
Blender Version
Broken: 2.80-e79bb957fc3
Worked: Ungroup, or copy the nodes inside the group and paste them outside of the group. Then group them again and set the ranges, names, types of inputs and outputs of the group node, also replace the other users of the problematic group used in all materials. This workaround is pretty tedious, works in 2.79b
Short description of error
Some material node groups in 2.80 from 2.7x files crashes in 2.80 but not in 2.79b
Exact steps for others to reproduce the error
To test if the appended node group is broken, translate and undo repeatedly, after the 3rd time it should crash 2.80, or also try changing the links or deleting nodes, or if you import the material that contains the broken node group it should crash when you select it in the material slot selector.
The appended blend file contains node groups that break in 2.8 but not in 2.79b or 2.78c
PS: I'm sorry I don't have an exact way of reproducing this error.

. It happened the first couple of times I opened the file, but then it stopped happening until I ran blender with--debug
. It seems to consistently happen with--debug
enabled.. When it does crash, it crashes when undoing a group node move operation.After the following operation
and then using
ctrl-z
to undo it, blender crashes. Here's the console output:Added subscriber: @lichtwerk
