The defringe module works well if I run darktable with opencl disabled. If I run with opencl enabled and apply the defringe module, I get a garbage image if the "sharpen", "shadows and highlights", or "crop and rotate" modules are also active. Turning off these modules restores the image to normal. I have not made an exhaustive test as to whether this problem exists for other modules; I think that white balance, exposure and highlight-reconstruction were OK.
Sample images are at: http://rapidshare.com/share/83863DFCF04B1727C8F6D755F84BA16E System is kubuntu-13.10, 64-bit, with the nvidia 319.60 driver from the ubuntu repositories. This does seem to be more of an opencl problem. I ran with "darktable -d opencl", and did not get any unusual message when the image went bad.
