Hmmm... so let's see

	Exception Type:  EXC_BAD_ACCESS (SIGSEGV)

so most likely an invalid pointer.  The call sequence triggering it is,
at the top end:

19  gnuplot_qt                    	0x000000010a85a2dc main + 912

That's the top-level call from gnuplot_qt's main() into Qt:

	application.exec();

This may have to be brought to the attention of the Qt5 people, but it
seems like the Qt event loop is still trying to process things after
they're no longer there.
