Bug 147263

I think this is the "Colors"/"Levels Adjust" entry in the image editor, right?
I can reproduce this with current svn. It is very weird:
The three pipette icons for "All channels shadow tone color picker", middle
and highlight  appear as three small dots.
Interestingly, if I then leave that tool, go to the "Curves Adjust", leave that
and go back to "Levels adjust", the first and third of the pipette ones
appear. 

I can confirm the weird behaviour when going to the Curves dialog.

Not reproductible here. I have installed a fresh computer to my son school yesterday, using current svn, and all is fine.

The png files used for picker color buttons are in digikam/data/pics/ and named :

color-picker-black.png
color-picker-grey.png
color-picker-white.png


3 files are installed in digiKam data folders from your KDE application install dir. Here under mandriva, we have:

 /usr/bin/install -c -p -m 644 'color-picker-black.png' '/usr/share/apps/digikam/data/color-picker-black.png'
 /usr/bin/install -c -p -m 644 'color-picker-grey.png' '/usr/share/apps/digikam/data/color-picker-grey.png'
 /usr/bin/install -c -p -m 644 'color-picker-white.png' '/usr/share/apps/digikam/data/color-picker-white.png'

in AdjustCurves plugin dialog code, we have :

...
    m_pickBlack = new QPushButton(m_pickerColorButtonGroup);
    m_pickerColorButtonGroup->insert(m_pickBlack, BlackTonal);
    KGlobal::dirs()->addResourceType("color-picker-black", KGlobal::dirs()->kde_default("data") +
                                     "digikam/data");
    directory = KGlobal::dirs()->findResourceDir("color-picker-black", "color-picker-black.png");
    m_pickBlack->setPixmap( QPixmap( directory + "color-picker-black.png" ) );
...

Which work perfectly...

The AdjustColors plugin works fine. It's the AdjustLevels plugin that fails. And now that you mentioned SVN, I have taken a look at the differences between these plugins: while AdjustColors is loading the picker icons from digikam/data/, AdjustLevels is loading them from digikamplugins/data/. At least on my installation this directory doesn't even exist.
