From the stacktrace I would say this is a bug in nux and not in unity.

Worth keeping on the radar. Mirco, could you investigate first, which conditions could help reproduce the problem. Then, look into the recent fixes that were made in nux/unity to correct object lifecycle and signal management problems.
