Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description 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. 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 the specific steps or actions you took that caused you to encounter the problem, and the behaviour you actually encountered (in as much detail as possible).
Thanks!
