 Replying to [comment:18 beastd]:
 > Concerning this ticket I agree with Derek it is and was about the
 behaviour of the decoder and thus not a duplicate of #2799.
 >
 > Actually we had a discussion about the fix of the behavior and this
 ticket on IRC and this ticket should have probably been re-opened. But as
 it turns out Micheal was faster and the whole behavior that was topic of
 this ticket now is gone for good since commit a05635ee.

 Pardon me, I wasn't very precise here. With behavior of the decoder I
 meant error behavior.

 Initially the decoder just detected it wrong and silently continued. Later
 it was changed to print an error and go on if `AV_EF_EXPLODE` wasn't set
 (commit 6904168c79f2).

 Finally there was commit a05635ee that implemented a conversion from CMYK
 to GBRAP in
 the decoder and replaced the changes of above mentioned commit
 6904168c79f2.
