Desired capabilities "language" not working with Appium V1.5.1

The problem

I need to test my application against many simulator with different language settings. For this, I set appium desired capabilities in the terminal by running: ➜ appium --language ‘fr’ in order to set the language of my simulator to “fr”. I tried also another method by creating different profiles in my cucumber.yml configuration file. Both methods are crashing my simulator(Please see logs below).

Environment

• Appium version: appium v1.5.1
• MAC OS 10.11.4
• Xcode v7.0.1
• cucumber v2.3.3
• ruby v2.3.0

I had same error with language capability and Appium 1.5.2. I have been researching the problem and I think it’s solved with https://github.com/appium/appium-ios-driver/pull/140.
