The question isn't about it being leaky, the question is attracting the 
attention of someone who can do something about it.  If someone had 
posted this on our bugzilla four years ago, it would also still be there 
today -- unless someone had actively looked through the list and brought 
it to someone's attention.  That e-mail was on the xen-users mailing 
list -- not the best place unfortunately for getting the attention of 
developers.  If no one did that for xen-users, why do you think they 
would do it for a bugzilla?
What full-time developers typically do is to go through the xen-devel 
mailing list every day looking for e-mails that are relevant to them.  
When they find a bug report they think pertains to them, they put it on 
their personal list and ask more questions about it to determine if it 
really is a bug, and if it really has to do with something in their own 
area or in someone else's.  When they determine that it is a bug and is 
in their area, they put it on their list of things to fix, and get to it 
when it fits with their current priorities.
The key process in this step is "detecting signal in the noise" -- 
finding what's relevant in what's not relevant.  On a mailing list, the 
"signal to noise" ratio is a function of how many messages there are and 
what percentage of them pertain to you; as Xen grows as as project, that 
ratio is lower, and so mail is sometimes dropped.
But the problem isn't actually better on a bugzilla.  If I'm scanning 
through bugs, I still need to find out which bugs are relevant to me.  
The "signal to noise" ratio in this case, however, is the number of open 
bugs -- which will grow linearly with time, as opposed to being a 
constant based on the size of the project.
What bugzilla is *worse* for is discussing what the problem is and 
coming up with a solution.  Mail is much more suited for that purpose.
What we need is people who report / complain about bugs / deficiences in 
a constructive way.  Ideally the reporter would keep "Keep bugging the 
list every so often until I'm told 'No'" on their own to-do list.  It 
would also be great if we had more experienced users helping to make bug 
reports better, and then helping bring bug reports / deficiencies to the 
attention of appropriate maintainers and developers.  Pasi I know has 
played this role, but it wouldn't hurt to have more people get an idea 
who might be the best person to talk to about a particular issue.
