kdebugdialog5 crashing on exit (FYI)

[René J. V. Bertin]

Hi,

I mentioned having crashes on exit with kdebugdialog5 a couple of days ago, deep 
in Qt territory. At first I thought the culprit was my implementation of a 
"KdeMacPlatformTheme" that inherits from the regular KdePlatformTheme.

Then I noticed that kdebugdialog5 also crashes on exit on Linux, when the 
KdePlatformTheme isn't present but the app is started with --fullmode (and does 
the same on OS X with the native platform theme).

Thiago Macieira referred me to a proposed change to refrain from unloading 
plugins (https://codereview.qt-project.org/#/c/140750/) and I can report that 
applying the patch indeed solves the issue for me (on OS X).
