CloneSlide generates errors

I got this error using CloneSlide of the Presentation object using the latest hotfix.
But I also got it using version
My guess is that there the error appears due to some difference in the color depth of the presentation from which I get the slide and the presentation to which I clone it, but I can’t be sure.
The error consequently occurres with the demoppt2.ppt from aspose when trying to clone the second slide.

[System.ArgumentException]: {System.ArgumentException}

Dear Mork,

Slide contains DIB image and System.Drawing.Image can’t open it.
Please check 1.5.12 hot fix.

That did it.
