Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, I suspect nothing can be done about this because you've provided little to no information. As such I'm marking this 'incomplete'.

You mention crashes; when a program crashes there should be a file in /var/crash/ which can you file providing debug information using something like

`ubuntu-bug /var/crash/_usr_bin[name-of-program-that-crashed].crash`

Further if you start it from terminal, you may see messages that are useful in helping to recognize why it doesn't start, if there is no actual crash report in /var/crash/.

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.
3. The behavior you actually encountered (in as much detail as possible).
Thanks!

If you have more information to provide, or believe my marking this 'incomplete' was in error, please leave a comment (with additional information) and change the 'incomplete' back to 'new'.

 Thanks again for taking the time to explore, report and help make Ubuntu better.
