I was trying to upload a simple file to drive using the files->insert API. Just migrated from .6 to 1.0 but still didn't work out. Can anyone please help? Warning: file_get_contents(compress.zlib:/ ...

Or does it upload sometimes? Does it happen with any other sort of files? Can you reproduce on any other sharepoints? My best guess at the moment would be that this is an eventual consistency problem ...
