Well I'm behind the stuff I'm doing because I'm interested in it. And
if some bugs are introduced by my work or derived by my work I'd like
to get them cleaned up in the end.
If I see that someone reports bugs which doesn't really address my
work at all I just forward them to the subsystem/maintainer who's "in
charge" (if someone can say it that way for an open source project)

I'm very sure that happens maybe it's just not visible to everyone
because there are so many open issues. (I just take myself as an
example here, I didn't do too much with other bugs but at least some
of my work closed 5 other bugs this year beside the bugreports I'm
getting directly)

Yes Adrian did a very good job with collecting every bugreport and
sending the mails to all corresponding subsystems.

Both have search buttons yes, but the lkml doesn't leave an unread
mail open ontop of the lkml as bugzilla does if you look for open bugs
in a subsystem.

bugzilla keeps the bugs open at least, at the lkml I use to skip days sometimes.
Many people who consider themself as maintainer of a subsystem are
assigned to a subsection on bugzilla, if it really doesn't work out we
have to change the corresponding maintainer.
If that maintainer doesn't know where to go with that bugreport he can
easily send it to the lkml and some people will recognize the
sender/email and pay extra attention to it (that's just how I think
about it)

well are there any bugs that cannot be forwarded/directed to a
corresponding maintainer?
Maybe I don't see something here, can you point me out to a bugreport
which cannot be handled at all?
As a reference I'll take following bugreport:
http://thread.gmane.org/gmane.linux.kernel/521185

the bug doesn't even mention what device is affected, asking for
further detailed information (dmesg) shows up what's left at least..
(in the meanwhile the bug even got solved)
