how to triage crashes?

[Walter Lapchynski]

I hope this is not a topic I didn't see discussed elsewhere, but I
have a crash that the upstream developer claims is resolved:
https://bugs.launchpad.net/ubuntu/+source/lxlauncher/+bug/1236109

How can I replicate this? Do I just go by the word of the developer?
