I tried to set up a new Wheezy/armhf image from scratch and I have good and bad news. the good: Gimp works without crashing when using the text tool. the bad: For some reason I'm unable to get keyboard support in lxde (via debbie it works fine in roxterm and gimp). Just for reference, I also created an armel image and I have the same problems there, so I'm pretty sure it's not architecture-specific, but I'm missing some "magic".
