Crash on switching "All locations"

[max]

Observed in build 8 on iPhone 3GS / iOS 5.1.1.

Steps to reproduce:

• tap the location (the location list appears)
• Edit
• +
• select any country, if it's not already selected
• turn on/off the "All locations" toggle

=> the app exits.

For me there is no problem with switching "all locations"


Ipad2 iOS 6.0.1

No problem here either...

iPhone4 on 5.0.1...

Might be a low mem issue on the 3GS...

My iPad2 behaves similarly, except it does not always exit and sometimes hangs. It is also running iOS 5.1.1. So, maybe it's something specific to the iOS version.

Max, this is a very important finding.

I cannot repeat the crash on my iPhone 4, iOS 6
However, I can see the crash logs in TestFlight - 3 times only from your account
The logs do not give me the exact place in the code where the crash occurs, but I will try to figure it out, hopefully.

It seems to me that I am using some new API available in iOS 6 only.

Thank you!

I have found the exact place in code where the crash occurs.
But...
I have no idea why.
Looking at the code and imaging possible cause that could make it crash I came up to nothing.
I wish I could repeat the crash.

Pasha,

I can lend you my iPhone, or do some test runs if you make a debug build. Let me know what you prefer.
