run_project_tests.py: TypeError: unsupported operand type(s) for +: 'NoneType' and 'list'

When I try to ./run_project_tests.py I get the following error:

Should I perform some additional steps before running ./run_project_tests.py? Or is it a bug?

Trying the current master branch on Arch Linux with system default Python

No, this is simply a bug in the testsuite. It happens since you have yasm installed and not nasm. I have a fix.

#12663 should fix this from happening.
