Bug 485345

SUMMARY
When selecting a custom icon for a folder (in the folder properties) most of those with a folder background have been made for changing background according to the color theme. However, once you reach a certain zoom level, some of them stop following the theme (and become blue again).
The wrong color stay even with refresh (F5), Dolphin reboot, linux reboot, or other color change.


STEPS TO REPRODUCE
1. Have a color theme with an other accent color than the default blue.
2. Put an affected icon (like "folder-build") on a folder (preferably a empty folder to prevent file's preview caching issues)
3. Maybe have an ordinary folder (default icon) next to it for reference.
3. In dolphin (or the desktop), have folders a little bigger than the default and watch if the color of the affected custom icon is blue instead of the color of the default folder icon (or than an unaffected folder icon).

OBSERVED RESULT
The color of some folder icons does not follow the color theme (above a zoom level). We know that those icons are suppose to follow the theme (contrary to some like "folder-green") because they do in the list of icon where we can choose from and they also do on a smaller level of zoom.


EXPECTED RESULT
Color should be apply in all level of zoom for every folder icon which is supposed to follow the theme.
