Hey fellas!

I am on Xubuntu 12.04. Kdenlive Version 0.9.6 (Using KDE Development Platform 4.11.2).
Used it for a long time without problem. All my projects are very simple - one image stretched to one mp3 file. Render it to a YouTube format using a preset. Suddenly yesterday my projects began to render without audio. Checkbox is checked (or "automatic", tried both). I did not change anything, maybe there was an update, I am not sure.

Anyone can suggest something?

Here is the detail of render of one of the files:

Started render process: "/usr/bin/melt" "consumer:/tmp/kde-louigi/kdenlivecS4138.mlt in=3954 out=12818 profile=hdv_1080_50i -consumer avformat:/home/louigi/Videos/VideoProjects/skeptic021_again.mp4 progress=1 f=mp4 acodec=libmp3lame ab=128k ar=44100 vcodec=mpeg4 minrate=0 vb=800k s=640x480 aspect=@16/9 mbd=2 trellis=1 mv4=1 subq=7 qmin=10 qcomp=0.6 qdiff=4 qmax=51 threads=1 real_time=-1"
Rendering of "/home/louigi/Videos/VideoProjects/skeptic021_again.mp4" finished

I limited it to guides so as to not render the whole project.
Seems audio is rendered with limmp3lame. Codec is installed, no recent updates to it. I have no idea what's going on. Projects that rendered fine before now also render without audio.
