Bone merge fail on Blender 4 with 1.7.2 using G2

[Mikael]

When importing a Genesis 2 character there will be an exception when it tries to merge the bones, this only happens on Blender 4, on 3.6 it works ok. File "C:\Program Files\Blender Foundation\Blender 4.0\4.0\scripts\modules\bpy\ops.py", line 109, in __call__
    ret = _op_call(self.idname_py(), kw)
RuntimeError: Error: Python: KeyError: 'bpy_prop_collection.get(key, ...): key must be a string or tuple, not int'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

daz studio 4.21.0.5, blender 4.0.1, diffeomorphic 1.7.3.1938

I can confirm the bug, this is also reported at the daz forum. Needs to be fixed in the stable too.

steps:

1. import G2F

Fixed in last commit, together with another Blender 4 bug.

Commit fdea7ea works fine, thank you for the fix.

I'm confused there’s no 1.7.2 in the branches and master loads as 1.7.3. Let us know or we can close as resolved if this is intended.

[Thomas Larsson]

I created a 1.7.2 branch on my home computer, but apparently I didn’t push it to the remote repo. But I think it is better to release 1.7.3 quickly, because there are other fixes that may be critical. E.g. #1865 which may be show-stopper in Blender 4.0.1.

[Alessandro Padovani]

Ok thank you.

It look like it is working fine now, minor issue though, it look like the version number displayed in Blender preferences is still 1.7.2 even if it is 1.7.3
