Thanks Nick. I had to reinstall my OS due to a rootkit virus/malware, masquerading as Google update / installer.. http://www.google.com/support/forum/p/Chrome/thread?tid=39a9c985ba746ec6&hl=en
(as was the suggested approach mentioned in many forums, that one cannot be very sure of cleaning up such rootkit malwares without leaving open any backdoors) Not sure if the malware replaced any of the binary files which appengine was using during startup (say, for example to check if there is an update available for app-engine, or other operations). Just wanted to share the possible reasons, back on this thread. I have a new setup now and back into development, of course without that old datastore (which had just sample/test data, so no issues).
