mne-python: Expected values from find_edf_events: missing annotations for EDF+D, but not EDF+C in 0.18

Using MacOSX and conda environment, I downloaded two versions of MNE. Using mne==0.17.2 and 0.18 current version, you take two sets of EDF files (EDF+D and EDF+C). They can be manually converted using edfbrowser.

For the EDF+D file it works for 0.17.2, but not 0.18.

Both versions work when the file is in EDF+C format though. Sample code is below. Test data is available upon request (@larsoner has seen the data though)

import mne

# in these two runs, only 0.17.2 matches for both files
# in 0.18, only the first annotations gets the full annotation list

if __name__ == '__main__':
    fpath = "./test_edfc.edf"
    raw = mne.io.read_raw_edf(fpath, preload=True)
    annotations = mne.events_from_annotations(raw)
    print(annotations)

    fpath = "./test_edfd.edf"
    raw = mne.io.read_raw_edf(fpath, preload=True)
    annotations = mne.events_from_annotations(raw)
    print(annotations)
