In cannot find any assert commands in the C code.   I don't fully 
understand what (sched:6186) is telling me.   The number changes each 
time I run the program.     Sched is the name of the program.    At this 
point I have no idea how to correlate the message to the code other than 
by not adding the widgets that seem to be affecting the message.   The 
program is never terminated by the assertion failure.  The only outcome 
is that the message is printed.    The program appears to run fine until 
it is closed.
