Most likely a server crash, but there is no way to debug it since to stack trace is available. There is a version of mtr in 5.1-rpl and 6.0-rpl which prints stack traces for core files it finds. Once that is merged to main, chances are that we can get a useful error message for this failure. Setting to "To be fixed later" in the meantime.
Description: Starting from Sep-16 rpl_charset failed twice in mysql-6.0. The push on Sep-16 has nothing to do with the code base (it was a change of .bzr-mysql/default.conf). Probably something changed on the box.
