xine on AMD64

Hi I'm using SuSE professional 9.3 on a AMD64. To be able to watch DVD's, I compiled Xine from sources with the needed packages. Compiling xine-lib and xine-ui doesn't make any problems, but after launching xine, I have the foolowing error message: Cannot open display "*". Segmentation fault. After I changed the DISPLAY Variable to 127.0.0.1 and exported it, the first error message doesn't appear, but I get the segfault again. The interesting thing is that DVD's could be read in kaffeine without problems, so I think the problem is in xine-ui. Has anybody a hint?? Thanx Al
