>Any clue ?

Yes, I have a clue. :)

A handful of apps don't compile after the recent API changes these 
commits:

523c1fd9 2013-12-22 [tqt3] Automated update from Qt3
d1b6b7be 2013-12-22 [qt3] Repair performance regression 
accidentally introduced with new style API

Tim is aware of the build failures.

The apps that don't compile with error messages related to the 
style API commits:

python-trinity
pytdeextensions (probably only because of the dependency on python-
trinity)
tdebindings
libtqt-perl
tde-style-qtcurve
rosegarden

If you are a code hacker, look at these commits to create similar 
patches:

a5826757 2013-12-23
7f8e73d6 2013-12-22

I tried patching python-trinity but I still kept getting build 
failures.
