Raff, thank you for taking the time to report this and helping to make Ubuntu better. Unfortunately, this report didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html and https://wiki.ubuntu.com/ReportingBugs . We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem,
2. The behavior you expected, and
3. The behavior you actually encountered (in as much detail as possible).

Thank you for your help.
