Hi,
Since the maintenance yesterday, I cannot read some specific items
from my datastore, using remote_api. The requests fail with HTTP Error
500: Internal Server Error, after 4 attempts by appengine_rpc.py. My
app is called scoretool, and the broken kind is called dns_lookup.
The oldest 4 entities were readable, so I updated them one by one, now
the broken entity is the oldest one, and I cannot get past it.
Traceback summary (full traceback at the bottom of this message).
Please note I'm not even trying to fetch data, only the keys from the
index.

The same problem happens if I try to read more than one entity:
Lookup.all(keys_only=True).order('timestamp').fetch(10)
Lookup.all(keys_only=True).order('timestamp').fetch(10, offset=300)
However, similar requests are working if they're using other indexes,
or other models.
Reverse order is okay:
Lookup.all(keys_only=True).order('-timestamp').get()
Different index is okay:
Lookup.all(keys_only=True).order('backwards').fetch(10)
Different model is okay:
Domain.all(keys_only=True).order('timestamp').get()
Full traceback from iPython:
In [8]: Lookup.all(keys_only=True).order('timestamp').get()
