On iOS i see intermittent crashes - "[GCKCastSecureSocket startSSL]: message sent to deallocated instance"

[GoogleCodeExporter]

The last line I see is:
[GCKCastSecureSocket startSSL]: message sent to deallocated instance

What steps will reproduce the problem?
1. Connect and starting a google cast stream
2. Open and close (press home button) quickly and multiple times...

What is the expected output?
The app will open, recconnect and close without any problems

What do you see instead?
The app will open and close fine but at some point I get a crash with the last 
message:
[GCKCastSecureSocket startSSL]: message sent to deallocated instance <memory 
pointer>

What version of the product are you using?
Running version 2.10.1 of the google-cast-sdk

On what operating system?
Tried both the iOS 9.2 simulator and a regular device iPhone 6s, running iOS 9.2

Please provide any additional information below.
I haven't been able to provoke this in the CastVideos example application, but 
as it is intermittent I cannot say that it isn't there.
Besides it seems to be from inside the google-cast-sdk, hence I´m unsure how I 
should be able to change this startSSL connection.

If you haven't been able to reproduce this with the CastVideos app, which app 
did you use? Also, can you provide any stream(s) where you're seeing this 
behavior?

I am working on an app for Blockbuster. google-cast-sdk (2.10.0) doesn't crash, 
but upgrading to 2.10.1 as the only change made the app crash. I enabled zombie 
detection to see what was the reason for this and that stated the reason for 
being this line. I have a stacktrace that maybe can help?

Are you by any chance releasing the GCKDeviceManager object while it is still 
in a connected (or connecting, or disconnecting) state?

I can confirm that we're also seeing this issue a lot after updating to the 
2.10.1 SDK.

As for GCKDeviceManager being released while it's still connected: In our case 
we keep a Chromecast controller singleton that's initialised in the 
AppDelegate. That controller keeps an instance of the GCKDeviceManager so this 
won't be released while it's still connected.

I've experienced similar crashes around 
'GCKPB_CastMessage_PayloadTypeIsValidValue' using 2.10.0 SDK. Unfortunately, 
all I have is the crash reports and have not been able to reproduce.

Update from us: we've downgraded to the 2.10.0 SDK with our new release and 
this source of crashes has vanished. Keeping with that for now.

If you need any further details on our project I'd be happy to provide them to 
you.

I'm seeing this issue, and I'm about to ship Chromecast support to an app with 
millions of users. Please help!

This was fixed in 2.10.2
