Segmentation fault on pytest exit when creating a SerializableObjectWithMetadata #1474
Description
A user reported that there is a segmentation fault when running pytest + objects with metadata + the "fs" (fake filesystem) capture system.
Repro:
import opentimelineio as otio
# Does not segfault if you comment out this "test"
def test_empty_fs(fs):
pass
def test_create_clip(capsys):
# can be child classes of SerializableObjectWithMetadata (Clip, Gap, etc),
# however other otio C++ classes appear to be ok (RationalTime, TimeRange,
# TimeTransform)
otio.core.SerializableObjectWithMetadata(
# also does not segfault if you comment this out
metadata={}
)Output:

(The warning is related to our use of imp and appears to be a red herring)
