Thank you for patience and testing.  The issue is apparent bug in KDE
which can do several calls to pthread_mutex_init() for process-shared
mutex, from different processes.  This situation is declared as undefined
by Posix and really is quite severe bug for unchecked implementations.

I committed the workaround as r297185.
