Got the root cause of "my" issue, i.e. kdenliveui.rc could not be found.
This was expressed as a warning on stderr, which I missed from within 
Kdevelop (duh...); obviously, this should be an error, not a warning, as 
kdenlive cannot run without kdenliveui.rc. I'll be looking  into why my 
build can't find the file although kdenlive/kdenliveui.rc indeed exists, 
and make sure kdenlive complains loudlier if it misses its .rc file.

(now this does not tell me why on Eath factory->container() returns that
weird 0xf0 value when it can't find the container in the UI definition;
but that's outside kdenlive, so I don't intend to investigate further on
it.)

Amicalement,
