Indeed, it requires sliced images, meaning it requires individual images
for the various borders and corners. It DOES NOT require those images be
in a combined image, though. So, to use your own decorators you just
need these "partial" images. To obtain them, you can use the slicing job
of the generator, or you do the slicing in whatever graphics tool you
have (Gimp, Photoshop, etc.). So you can achieve everything necessary
for your custom decorator without running image jobs of the generator.

So just do the slicing and make sure everything is working. You can
delay the combining for later.

This is not quite right, only if you restrict your view of what the
"manual" is. Like with most other programming documentation, the qooxdoo
manual has "user guide" sections (like [2]), and "reference" sections
([3]). User-guide sections try to give an introduction and a general
feel for a particular aspect, but don't give all the details, which I
think is necessary to convey the general idea. In order to master such
an aspect you have to consult both.
In this case, the reference [1] is completely explicit about "prefix"
being required (and the "Image clipping and combining" page [4] you are
probably referring to explicitly *links* to this reference section!).
What I do want to concede in this case is that an error message of
"object of type 'NoneType' has no len()" is far from being instructive,
and you may want to open a bug for this.
