Just upgraded my Kubuntu 11.10 64bit box to kdenlive 0.8.3+git20111111.08fd8d1c-0ubuntu0~sunab~oneiric1. The timeline now does not show transitions anymore; there is only a dark yellow lines where formerly the transition effects happend to be. Selection is not possible anymore.

Just updated Kdenlive today to 0.8.3 and have the same problem.

There is a slight problem at the moment and a bug report has been issued here:-
