gr::AuthAgent::CheckHttpResponse exception about grive2

[vitalif]

Please retry with the latest master, I suppose it's the same bug as in #5

[mkauzlar]

Seems ok now. I have tested it on a couple of files and don't get the error anymore

Happened to me as well today:

Also, when I upload files, I get a lot of 412 response:

Please retry with the latest master, it should print response body of these 412's - maybe we'll learn something about them at last...

[vitalif]

You can also try the new --http-log file option to have all HTTP responses logged and then provide me the details from the end of that file.

[vitalif]

I'm now also getting a lot of intermittent 412 errors myself... But I don't yet understand why. They usually go away after restarting grive, but I end up with duplicated files...

[vitalif]

I believe 412 is fixed in master by using multipart uploads - now file metadata and contents are uploaded in a single request so the situation where the second request "does not see" the result of the first one due to the async nature of google drive service is impossible.
Please test and reopen the issue if you still experience it.
