Describe the Bug

Certain files cause the following to be logged:

{

  "userAgent": "--",
  "version": "29.0.1.1",
  "data": {
    "app": "integration_google"
  }
}

I am unsure which files are causing this because no filename is logged.

Expected Behavior

Files are transferred without errors.

To Reproduce

I'm unsure about the repro because I have no sample to share, however I suspect these files are documents. Searching for the error in GitHub returns multiple results, and it seems that there are ways to properly get them.

An example (in Python, sorry): https://github.com/dixonl90/tuxdrive/blob/e71ca0da16b6e03a05b21ef6b58109deb7d2b03d/tuxdrive#L311-L315

			if ("Only files with binary content can be downloaded." in str(ee)):
				print("File not in binary content. Trying the export method.")
				request = service.files().export_media(fileId=file_id,mimeType='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
				fh = open(output_file,'wb') #io.BytesIO()
				downloader = MediaIoBaseDownload(fh, request)

No source files or tests are named. Start by tracing the integration_google Google Drive download request shown in the log and how document files are handled; compare the regular media download with the export behavior described in the report. Done means affected documents transfer successfully and the failing file can be identified from the logs.
