The icons of 'kmix' and for 'nepomuk-indexing' are invisible in the top bar. It looks like some empty space in the top bar between left screen border and first icon (Available Devices), but touching in this area will open the missing 'kmix' or at startup the 'nepomuk-indexing' dialog. Reproducible: Always Actual Results: invisible icons Expected Results: visible icons This happens on basyskom-plasma-active-archos-gen9-omapfb-tablet-mer-testing-release-rc3 based system.
I can confirm this with the Wetab image as well.
Seems fixed in current Master
