Very annoying Exception in appengine/api/app_logging.py : TypeError: not all arguments converted during string formatting

[Amine Azariz]

App Engine Prod Server. / Python 2.5

In the logs, I see that error stack for many requests. The calls succeed but app engine internal logging module logs this, everytime.
