I just have the same problem.
It appears in a fresh new installation and in upgrade too.
I temporally fixed it making a downgrade via FTP:
– Delete the actually Jetpack 2.0.3 plugin via FTP;
– download the 2.0.2 version from here;
– installed de 2.0.2 version trough FTP;
– activate it;
– done!
Works fine for me, no issues right now.
Hope you find it useful. Waiting official fix!
