I'm not sure what mutex would be getting locked at that point. If
you're rebuilding binaries, could you try building with -g and get a
stack trace in gdb when this happens? If it's in one of the libkrb5
mutex-handling macros, the mutex object we use should include a file
name and line number where the mutex was last locked or unlocked;
that would be useful to know too.
