Some changes were made to the TaskManager class. There is a fork that is being kept more up-to-date than what is found at kde-apps.org / kde-look.org. https://bitbucket.org/flupp/smooth-tasks-fork/ There is a patch there that seems to address the issue: https://bitbucket.org/flupp/smooth-tasks-fork/issue/13/compiling-fails-in-4780#comment-902594 Reproducible: Always
Ok,I created a smooth-tasks-fork live ebuild adding the patch mentioned and could confirm that it compiles fine. I have to test it, if all is fine I could tar and share the ebuild here. I would vote to add smoth-tasks-fork to tree to take the pain from smooth-tasks users.

Snapshot is patched to build with + kde 4.8. Remove old snapshot violates naming scheme. Fixes bug #400863.
