The linux versions (ht and normal) seem to be broken with the latest 
Trunk image[1] (and any other image I tried). I suspect that the rendering 
code is causing this, because the image becomes unresponsive right after 
some UI changes, and uses 100% CPU.
I tried to open a browser, but got a few red squares with yellow crosses 
along with some blurred gray lines instead. Sometimes it stops responding 
after the first mouse click.
