Well, I've heard that FC7 is using an unpatched QT 3.3.8, which has a
known bug that causes Myth applications to segfault upon exit.  If KDE
doesn't handle a client's segfault appropriately, then you'll have to
either patch QT or downgrade QT to 3.3.7.

Again, if this is the problem, the behavior isn't caused by Myth or by
any Myth settings.  Instead, it's caused by a bug in QT (that causes the
segfault), and, IMHO, a bug in KDE (that causes KDE to crash when a
client--perhaps only a client started with the auto "startup"

In other words, there is no Myth setting that determines what happens to
X when Myth terminates and there is no code in MythTV to terminate X. 
So, please move along.  There's nothing to see in the Myth settings. 
Try looking at X/X configuration/desktop environment/DE configuration... :)
