>  When pasting from Firefox, change first the encoding to Unicode (UTF-8),

>  3. Configure the preferences in Gedit to use Dejavu Sans (or Sans), which
> is the default in Dapper.
>  4. Load testtext.txt into gedit (use File/Open, or even "gedit
> testtext.txt").
>  5. In most cases, gedit crashes straight away.
