7+' Screens crash in render and play!

Hi!

I have Ubuntu 10.10 and Kdenlive 0.7.8

1. I have 13 video tracks with 12 videos (each in 320x240)
2. Preject settings (HD 720p 30 fps)
3. with 12 wideos in original size to make one big screen in 1280x720 -> http://img835.imageshack.us/img835/8894/12344111.png

Bug - I can play it with "Forward 1 frame" and "Rewind 1 frame" but what push "play" Kdenlive crash!

--- Details: Executable: kdenlive PID: 11168 Signal: 11 (Segmentation fault)

That number 11168 is changing all the time to different

But it can be render, only when appears the 7'th screen - rendering crashes and stops, and video is no longer fore first seconds...

Is this could be KDEnlive bug, that it can't render and work with more then 6 video's at one time?
