A lot of novice users file bugs that tend to be long, rambling, and full of irrelevant information, which makes them hard to parse. We may benefit from using a standard template in the description field that guided users through how to format a reasonable bug report, like this:
<One sentence summary of the bug>
STEPS TO REPRODUCE
1. <First, I did this>
2. <Then I did that>
3. <And then I did this other thing>
<Here's what I wanted to happen>
<Here's what actually happened>
<Here are the configurations/software versions/Linux distros/conditions under which it doesn't happen>
<Logs and other information that may be helpful>
Any specific products and components should of course be free to tweak or override it.
The Document Foundation's guided bug entry UI is really excellent: https://bugs.documentfoundation.org/enter_bug.cgi?product=LibreOffice&format=guided
We might consider doing something similar.
Please note that at this time we don't really have a Bugzilla maintainer and as such keep the number of customisations to the codebase to a minimum.
If you're interested in looking into the necessary code or configuration changes please contact me.
