Re: please, where has xconfig KConf option documentation gone with linux 4.8's Qt5 / Qt4 xconfig ?

[Boris Barbulovski]

hi Randy,

Frankly I don't have answer to your questions, but I did reproduced
the issues you described.

And found that:

* `Show Debug Info` menu item was(created, but) not added to the menu.
* if the `showDebug` setting was set to true, the the initial widgets
state will not be set correctly.

I did a patch of those issues fixed.

If you choose to keep the `showDebug` stuff in, you can checkout/test the patch.
