Providing a lot of information in a bug report is useful. It helps the developer work out what's wrong. However, you should be careful not to reveal too much information as one submitter did to Gnome in
their bug report. Have a look (if you're not in work) at the .xsession-errors at the end of their report to see what movies they were playing.
Update: mind you, at least they were vaguely covert, compared to the brutal honesty of this report. Thanks to Florent Bayle for that link.
