I have made a similar post, because I did not know yet, that Alan71 has posted something similar to my problem. I also get the same error as he has shown in his screenshot above, which I also mentioned in my bug report.
I have the same expected behaviour as Alan71. Also my Space (Now called Channel) has been also 3 years old, as well.
But check out my post for more information. I think my import concerns more the images not loading up compared to Alan71, if I understand him correctly.
