SUMMARY:
***
Gwenview is incompatible with KDEs own default themes.
***

STEPS TO REPRODUCE:
1. Change the themming to Breeze Twighlight (I assume everyone is hurting their own eyes with dark themes, so please change it now).
2. Click "Colors & Themes" and change it to "Breeze Classic" (light inside, but dark panels).



OBSERVED RESULT:
3. Elements inside Gwenview DO NOT obey the set up themes. The panels are dark, yes, but the inside should be... WHITE/LIGHT. Just like in the "STEPS TO REPRODUCE".
So where is the problem. Using Gwenview reveals that when you browse photos the text in the left panel changes suddenly to obey the dark theme (but we set the light insights!) and the text CHANGES FROM DARK/BLACK TO WHITE. END Result: WHITE TEXT ON WHITE!


EXPECTED RESULT:
Gwenview obeys KDEs DEFAULT themming (provided by KDE itself). Don't suddenly change the theme inside Gwenview in the middle of its usage. Do not revert the theme just right after we start use Gwenview usage. Stick to the chosen KDE themming. The theme reversal only happens in Gwenview. No other "KDE Gears" do this, they always stick to the chosen KDE theme.
