Cannot load .vol file created from .stl

Note: because of GitHub restriction, you will have to rename led.txt to led.stl and reproduce.txt to reproduce.py.

I have the following .stl file which converted to .vol properly in the past using the attached script.

When I try to run the script it fails with the following error:

    volmesh.Load('led.vol')
IndexError: basic_string::substr: __pos (which is 18446744073709551615) > this->size() (which is 7)

However if I run the Netgen GUI, I am able to import the created .vol file and view it without any error.

Hi,
I cannot reproduce this issue with the newest version. I think it is fixed in the latest master. Please reopen if not.
