It can be very helpful when experiencing a crash to send a copy of the crash log generated by the system. Copies of crash logs are in ~/Library/Logs/CrashReporter (i.e. Home > Library > Logs > CrashReporter) and are named after the program. Quite often they point to the place the bug is located. Another way to help is to describe the problem more specifically. In this case it would be nice to know the URL of the web page which is causing the problem so that I can try to reproduce it. Thanks!
