FATAL EXCEPTION [UnityMain]

I got the following report, and was hoping someone knows what it would be. The error happened on Galaxy S5 shortly after user upgraded to version 5.0 based on their report (I don't have a phone with the OS).

Someone here: http://answers.unity3d.com/questions/338661/android-segmentation-fault-issue-signal-11.html wrote "It turned out that we had class (normal class, not Monobehaviour) that has [System.Serializable] attribute and one of our programmers implemented default constructor in that class." I have this as well, is it a problem?

I'm including entire stack except took out the name of my package.
