Because of the typo in if __name__ == 'main', the condition never evaluated to true, thus main() function was not called upon the first invocation of the script. But any subsequent invocation of the script succeeded because of the app caching - the source code was not evaluated anymore, the App Engine called main() directly (the App Engine knew that main() was present in the script). So the "strange" behavior of my app was entirely my mistake. The reason for the first problem (occasional blank pages) became obvious to me now.
