[sup-devel] sup 0.14: Encoding::UndefinedConversionError from thread: load threads for thread-index-mode
Sup 0.14 fails for me just after the start with the following exception:
--- Encoding::UndefinedConversionError from thread: load threads for thread-index-mode

I noticed that this exception looks similar to a report from 2011:
