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: 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). Thanks!

Thank you for using Ubuntu and taking the time to report a bug. Your report should contain, at a minimum, the following information so we can better find the source of the bug and work to resolve it.

Submitting the bug about the proper source package is essential. For help see https://wiki.ubuntu.com/Bugs/FindRightPackage . Additionally, in the report please include:

1) The release of Ubuntu you are using, via 'cat /etc/lsb-release' or System -> About Ubuntu.
2) The version of the package you are using, via 'dpkg -l PKGNAME | cat' or by checking in Synaptic.
3) What happened and what you expected to happen.

The Ubuntu community has also created debugging procedures for a wide variety of packages at https://wiki.ubuntu.com/DebuggingProcedures . Following the debugging instructions for the affected package will make your bug report much more complete. Thanks!
