iOS port crashes when using Storage.getInstance().clearStorage()

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Have some data stored using the cn1 Storage API.
2. Then call clearStorage() to clear the storage.
3.

What is the expected output? What do you see instead?
The storage data should get deleted.

What version of the product are you using? On what operating system?
Codename plugin ver 1.0.4 and using on Mac OS running in the iPhone simulator. 
The behaviour is re-producible on the actual iPhone device also.

Please provide any additional information below.
Error Debug output on the console is printed below:

Hi Shai,

I tried again after re-buidling the app. However it still crashes when I try to 
clear data using clearStorage(). Here's the debug output:

Did you download the sources? 
I've changed the method call signature to [fm contentsOfDirectoryAtPath:ns 
error:nil];

If it doesn't include the error argument that might be the problem. I just 
updated the server again and verified that this argument made it into the build 
distribution.

Yes, I downloaded the sources. The source file contains this:

 NSArray* nsArr = [fm contentsOfDirectoryAtPath:ns];

So let me re-try one more time and see what the source contains.
