Hello there, It was reported to me that ktechlab and piklab(both still using kde3 libs) are crashing upon launch on F-12. I confirm those crashes and I suggest it's some modifications you made to the fedora kde3 libs. Both ktechlab and piklab still have a long way before we see a stable qt4 version of each, hence I would appreciate if you can look why these apps are failing to pull proper kde3 libs. thank you Chitlessh
