Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
Quite often software is built in a batch or on a "headless" server, where DISPLAY is not defined. The self-tests should detect such situations and not fail. Unfortunately, that's not the case with 6.4.0-3:

I'm not sure, whether it works properly on a local display -- probably not...
