ouch.. not sure... I have tear installed, and piles of other bits and pieces that I test... Just enabled the extras-devel repository, and installed Digia @web first, then installed digia @scene. @ web is also cool; I had none of the crashing problems mentioned by others, and surfed for almost an hour this afternoon on it. A little slow compared to tear, (reallly slow on gmail!) but a fun tool to play with as it is developing.
