The problem is caused by DeviceN color space that appears to be incompatible with /SoftMask implementation. .begintransparencymaskimage operator takes the current color space as a blend color space, which appears to be incorrect. Additionally, DeviceN as a blend color space is not implemented. Transparency issues are not exactly my specialty. The purpose of the following patch is to show where the problem happens rather than fix it. With the path applied, the file runs to completion. otherwise, it fails at the line gstrans.c:621 starting a cascade of errors.

Just a note. DeviceN cannot be a blending space for a softmask. The tint transform must always be used. The reason is that the eventual output of the softmask is always a monochrome buffer. Created attachment 5987 [details] 05000CBF327.pdf These are fixed with the color changes that exist in the icc branch. I will close this bug when the merge occurs. Merge is likely to be in May 2010.
