[Mne_analysis] error with interpolate_bads

[Sophie Herbst]

Dear list,
I am running into errors when trying to interpolate bad channels.
I have tried it on different versions of my M/EEG data, but the problem is
there from the raw import (data recorded at Neurospin). Running
interpolate_bads on freshly imported data (no maxfilter applied) gives the
errors below. Same after applying Maxfilter (and adding a bad MEG channel).

Any help would be greatly appreciated.
Best, Sophie
