Crash by fetching a preference

[ESinyak]

I found the following crash in the Crashlytics. Can't reproduce on my test devices. I use 0.9.9 version. Can update to 1.0.0-BETA-2 possibly solve it?

Do you have any ideas why it may happen?

Hi!
Thanks for issue submitting.

Can update to 1.0.0-BETA-2 possibly solve it?

Yes, this kind of problem has been solved in 1.0.0 beta 2.
Please, upgrade your dependency.
Also note what 0.9.9 and 1.0.0 beta's is not backwards compatible if you use built-in key and value encryption.

Regards,
Alexander
