When I first tap an SLC icon, nothing happens. On the second tap, it works. If I tap again, it works again. But if I tap another SLC icon, it again does nothing. It seems like the icon has to somehow be "selected" first in order to work.
I am not able to reproduce this bug. Which image did you test? There is a problem in nepomuk that makes everything that uses it (slc for example) be slower. I think the devel and testing images from 2012-03-27 have this problem fixed. If you are using older images they may still contain the bug.
It generally works by now (basyskom-plasma-active-wetab-exopc-tablet-mer-testing-120913-1410.iso). The only annoyance which persists is that when the menu of one SLC icon is still open and I tap another one, the menu closes, but the other one's menu only opens after another tap. This may become more annoying later if a user does not know for sure which icon contains the function she wants and just tries two or all three icons one after another.
