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.
