Okay, I modified my previous example to show what is happening.  I highly 
doubt this is my fault, but if it is, I'm sure you'll correct me ;)

I ran it through gdb to see where it was dieing... the last few items in the 
backtrace gave me the following:

Program received signal SIGSEGV, Segmentation fault.

Note. If I comment out line 64 then the program works fine and won't segfault.

To reproduce what I did, leave line 64 in and then launch the program.  Hit 
"Launch" as many times as you like.  Now hit "Fire".  All the "child" 
(although parentless) objects get closed/deleted.  Now hit "Fire" a second 
time.  Boom!

Another way to reproduce it is to create some child objects by hitting launch.  
Now close the child objects so they get deleted appropriately.  Once all 
child objects are closed, hit "Fire".

Well, please let me know what you find.  Even if there is just a work around, 
it would be nice to know.
