I hope that this isn't a RTFM problem, because it is so basic, why should I be the first to encounter it?
The renderer produces a short invalid file as soon as I add a title clip.
The setup: Ubuntu 12.04, 64 bit, first with the "standard" kdenlive version (0.8.something) - I since updated to the sunab ppa, i.e. 0.9.4.
I start kdenlive from the command line using
export LANG=C; kdenlive
to get the english menus etc.
I add a clip and change the profile to the suggested one (depending on the resolution).
I pull the clip to the timeline (Video 2), expand the selected range to fit the entire clip, press "Render", "use selected zone", "render to file".
The rendered clip works perfectly.
I add a title clip, enter some text.
I put that clip on the timeline (Video 1) at position 0. kdenlive automatically adds the transition "Affine".
The "project monitor" shows the expected result: some text put over the clip.
I hit render...
The render finishes immediately. The resulting file is 0 bytes long.
The terminal output of the two renders looks quasi identical, except for the line "NULL item." before "//STARTING RENDERING:" in the second one.
The melt -version is 0.8.8.
I tried various input formats, various output formats, all with the same (i.e. no) result.
Any hints?

P.S.: It there a "thank you, developpers"-thread somewhere? :-)
That would have been too easy. Some result. The renders aborts as soon as it tries to render the title clip.
I found in the man pages the KDENLIVE_RENDER_LOG variable, which produces a log file of your render.
If I start kdenlive like this:
export KDENLIVE_RENDER_LOG=1 ; export LANG=C ; kdenlive
I get the attached log file.
As you can see there, It renders a few frames, then gets to the title and the progress counter stops.
The only "strange" thing in this log file IS the definition of the title:
<kdenlivetitle width="1920" duration="125" height="1080" LC_NUMERIC="C">
The opening bracket is replaced by it html entity (<).
Just wondering... it would be nice to have it working.
