E.g. for conversion into CMYK it should be enough to select
Image -> Mode -> CMYK
The necessity to add alpha is a technical solution and not easy usability.

I do not exactly remember. In my second session it crashed after
activating/deactivation some channels.

LIBTIFF, Version 3.8.0

In my second session (after trying around some time) I was able to
convert a RGB.jpg into a CMYK.jpg. But 'save as' tif was not possible -
it did not save the file to disk.
At a next try (fresh start) I opened the CMYK.jpg, it asked for
conversion from one CMYK-ICC to another and then looped in throwing
errors 'Please add alpha to image before converting'. I had to restart X
with cntl-alt-backspace - X was dead.

Here is the point in this discussion where I should subscribe the
developer list of cinepaint. I can take the task of testing.

 I will raise a critical bug at Debian-BTS.
