Comment(by anonymous):

 Confirming this harmless nuisance on my backend; happens very frequently
 and looks like a race condition to me.  BT shows one thread at
 main.cpp:959, just after "delete gContext".  Second thread is
 MythSocketThread, which segfaults as it was processing the
 CLEAR_SETTINGS_CACHE initiated by main.cpp:955.  It segfaults because
 "delete gContext" at main.cpp:957 destroys MythDB object while the second
 thread is using it.  Hack approach might be to throw a usleep in here to
 reduce the frequency of these segfaults, but certainly there are better
 solutions.
