black image on proof with preceptual rendering intent #24

Closed beku closed 8 years ago

The bug is visible in oyranos-image-display and oyranos-icc. After switching the rendering intent, everything works fine. It might be a upstream issue in lcms2, but needs more investigation.

For this fix, the mpe tag generation is disabled. Proofing with perceptual intent is working again. This bug needs eventually to be reopened when float mpe profiles are supported again.
