It won't happen often, but when it happens, it will happen repeatedly and over something very small, like deleting a column, word or page, or even adding bullet points. I'm on CS6 now, but it happened on CS5 as well, I thought upgrading would stop it. Sometimes there are ways around it, but generally it just crashes a lot and severely frustrates me.
I've tried splitting files, exporting as IDML, and deleting the ID preferences & save data.
Could you please let us know the issue is file specific or not ?
As per the log file, I wil suggest you work on the fonts on your system as they may be causing the issue.

You also need to apply the 8.0.1 patch.
Try recreating the crash with preflight turned off, sometimes preflight tends to crash indesign
