Where can I find out more about Blob?
gk.chart.data is a Blob which contains a GZIP compressed byte string.
After decompression I convert it to unicode:
url = unicode(gk.chart.data.decode('zlib'), "utf-8")
Here is AppEngines response:
File "C:\python25\lib\encodings\zlib_codec.py", line 43, in
zlib_decode
output = zlib.decompress(input)
error: Error -3 while decompressing data: incorrect header check
