[Brett Cannon]

Brett Cannon <brett at python.org> added the comment:

Attached is a patch that fixes where the error occurs. By opening the
file by either file name or file descriptor, the problem goes away. Once
this patch is accepted then PyErr_Occurred() should be added to all uses
of PyTokenizer_FindEncoding().
