There is a hard "trace[0]" in that line. I'm still wondering how the stacktrace could be empty, though. Looks like some VM race condition? It isn't critical but a check should do no harm.

Note, the code has been for this like ages. At least it feels like ages. It only happend just now for the first time ever and I'm unable to reproduce. Really looks like a VM thing.
