Does it happen only with specific video files? If so, providing samples of such files may be helpful.

It happened on a DVD that I had copied 1-1 to my data disk drive some
years before. I was looking at programs to convert all my video files to
h.264 format. On opening the first 1GB VOB file the crash occurred. The
whole DVD (Jesus Christ Superstar) is 5 GB so it is too big to upload
using my 320 kbps upload speed. It could be caused an incorrect idx
file?

The DVD had two main audio stream and other characteristics were:
Video
codec 4C: MPEG
image size: 720x576
aspect ratio: PAL 16:9 (64:45)
frame rate: 25.000 fps
frame count: 160473
total duration:01:46:58:020
Global Motion Compensation: No
Packed Bitstream: No
Quarter Pixel: No
Audio
codec: AC3
channels: 6
Bitrate: 56000 Bps/ 448 kpbs
Variable bitrate: No
Frequency: 48000 Hz

Sadly this information is not really helpful. It would be more helpful if you had a small sample file you could upload.

If you can reliably reproduce this, youcan also run pitivi in debug mode:
PITIVI_DEBUG=*:5 GST_DEBUG=2 /usr/bin/pitivi > debug.log 2>&1

Then compress and attach the log file to this bug report.

The problem disappeared probably due to the updates in Natty. I cannot
reproduce it anymore.

My bug-report was marked duplicate of this. I have attached the log requested here in #4. Please log at it at: https://bugs.launchpad.net/ubuntu/+source/pitivi/+bug/759859

Let me know if you need anything else.
