This morning I added a test script to the Apport bug patterns.
This finally allows you to reliably test a new bug pattern before you actually
commit/push it. You can invoke it with either a .crash file, or a Launchpad bug
number:
$ ./test-local 122988
Matched bug pattern: https://launchpad.net/bugs/122637
$ ./test-local /var/crash/_bin_bash.1000.crash
No match
