I’ve tried the dll in a windows installation, and it makes the storage type selection appear blank. I think the problem is the signature too: a signed app can’t load unsigned dlls. I’ve tried to sign it with a self-signed certificate installed in the system and it don’t solve the issue.
@kenkendk: How about integrate the workaround in the master branch until the new api is used? so it will be in the next version. It should no cause problems in correct onedrive accounts.
