[alexanderkhitev]

Hello Firebase team! I saw that one of the users had an app crash. This happened in build with Firebase 4.2.0 Please tell me how can I fix this?

Here is app crash logs.

May be a variation of #281

I should get better on aims

@alexanderkhitev, I'm going to close this issue for now since we've seen no new reports and #281 was resolved. If this is still an issue after updating Firebase to the latest version, feel free to reopen.
