Feel free to change this to:

```python
from socorro.external.crashstorage_base import (
    CrashStorageBase,
    PolyStorageError,
    PolyCrashStorage,
    FallbackCrashStorage,
    PrimaryDeferredStorage,
    PrimaryDeferredProcessedStorage
)
```
That way, if we change the word "external.crashstorage_base" it doesn't screw up the indentation making you think the whole thing has diffed.
