Well gdb here was showing crashes in code with kapp access in a few other
places in the plugin.  I was sure this was not the only problem, but the
kapp is a problem none the less, so its not as nonsensical as you wish it
was.  I was just reporting where my evidence was showing, if you disagree
great, no reason to chastise me for actually trying to deal with the
problem.

But why did this pop up so late here for all of us, also why does
reverting the Qt widget plugin code to pre-C++-ification also fix the
crash as reported by Ferich?
