I'm working on an application which started crashing after updating
"ruby2.1-2.1.2-7.23" -> "ruby2.1-2.1.9-8.3.2".
"ruby2.1-2.1.9-8.6.1" doesn't solve the problem.

I can't provide the sourcecode of the application, which is pretty bad (I
know).
Nethertheless I wanted to ask if someone's able to tell something from the
attached Ruby stacktrace.

Full stacktrace attached as file.

Thanks!
