Yes, confirmed. You see the message when you open images with existing 
history stacks in a more recent git version. The issue appeared when 
module exposure recently got support for multi-instance and blending.

Unfortunately modules without blending store an all-zero blend parameter 
set into their history stacks. At first sight that looks OK as these 
data are normally never used. However, when at a later time this modules 
is allowed to do blending it gets confronted with invalid blend 
parameter settings. That's the message you see. Luckily besides the 
warning nothing bad happens.

I will take care and fix the issue.

Learning: never assume that NULL or zero always acts in a neutral way.
