Indeed, there is a bug in Python. It can be reproduced without lxml:

$ ./python -c "raise SyntaxError('error', (b'file', 1, 2, 'text'))"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
python: Objects/unicodeobject.c:397: _PyUnicode_CheckConsistency: Assertion `PyUnicode_Check(op)' failed.
Aborted (core dumped)

It has been fixed in 3.7+ by issue37467, but the fix was not backported to 3.6.
