Build a crash database for Ubuntu.

Quoting Matthew:

Microsoft, Apple, and Mozilla have dedicated crash tracking systems, separate from their bug trackers. This has multiple benefits, when compared with Launchpad and apport:
- people don't need a sign-on account, of any sort, to report crashes
- developers aren't spammed with e-mail notifications about duplicate crashes
- non-developers aren't spammed with e-mail they don't understand after reporting crashes
- the error message, explaining that a window just disappeared because the application crashed, appears in release versions of the software -- not just alphas and betas
- contributors can easily see which are the most common causes of crashes
- contributors can easily see how reliable their software is compared with previous versions.

For these reasons, Ubuntu should have an error tracker too.
