Short description of error
When triying to import a DXF file with blocks. The default settings work well. However, if changing the option for block from linked objects to group instances, I get the following error:

Python: Traceback (most recent call last):

It looks like there may be some old code that needs to be updated

Exact steps for others to reproduce the error

Go to {nav File > Import > Autocad DXF}
Change the option block from Linked Objects to Group Instances
Try to import the attached .dxf file (DXF file with blocks).
Circle_Block.dxf
