Crashlytics does a lot of work when built in release mode to try to give you un-obfuscated stack traces. Make sure you have configured it completely in build.gradle:

buildscript {
    repositories {
        maven { url 'http://download.crashlytics.com/maven' }
    }

    dependencies {
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.14.7'
    }
}
apply plugin: 'crashlytics'

repositories {
    maven { url 'http://download.crashlytics.com/maven' }
}
