Comment 6 for bug 1240819

With ffmpeg I converted all audio file in ogg format. ffmpeg found and fixed errors in original audio files.
I substituted all audio file in my project.

Openshot when I request preview for the first o second time, crashes.

Now, at every crash in the openshot output I get some lines of this message:
[mpeg @ 0x11bdaf20] max_analyze_duration 5000000 reached at 5005000

and a last message:
Errore di segmentazione (core dump creato)
