Blender crashes on exit of game engine Ubuntu 8.04

Been using Ubuntu for a few weeks now and I am enjoying it. I managed to get blender working (except there is no console…?) but whenever I exit the game engine it just freezes and if I minimize it, I can’t load it back up.

Anyone else had these problems and if so have they sorted them?

look its memory usage there is a terrible memory leak bug: https://projects.blender.org/tracker/index.php?func=detail&aid=17858&group_id=9&atid=125
