I'm trying to get my todo lists out of text files and into GTG. Mostly
I'm still trying to figure out how everything hangs together.

As one step along the way, I thought I'd write a script to dump all of
the tasks. Here's what I ended up with.

import sys

from GTG.core import CoreConfig
from GTG.core.datastore import DataStore


def get_requester():
    """Get a `Requester` object that we can use to manipulate the store."""
    config = CoreConfig()
    data_store = DataStore()
    for backend in config.get_backends_list():
        data_store.register_backend(backend)
    config.save_datastore(data_store)
    return data_store.get_requester()


def main(args):
    requester = get_requester()
    for tid in requester.get_tasks_list():
        print str(requester.get_task(tid))
        print
    return 0


if __name__ == '__main__':
    sys.exit(main(sys.argv[1:]))


The get_requester bit is cargo-culted from GTG/gtg.py. I don't really
understand the backend registration, nor the need to call
save_datastore before I actually do anything.

Here's what I get when I run the script a few times:

Sometimes I get 2 tasks, sometimes 3, sometimes I get an exception.
What's the deal? Am I using the API incorrectly, or is there some
buggy threading interaction going on?

Thanks,
