Can you get strace output or a stack trace from the faulty dbus-daemon
to see what it's up to, similar to on
<https://bugzilla.redhat.com/show_bug.cgi?id=667787>?

If you look in /proc/PID/fd (for the pid of the faulty dbus-daemon), does
it have a large number (hundreds) of file descriptors?

Do you use KDE? That Red Hat bug involves a KDE process that leaks D-Bus
connections.

There is also a D-Bus bug where dbus-daemon can busy-loop if it is watching
too many file descriptors,
<https://bugs.freedesktop.org/show_bug.cgi?id=23194>. The changes to fix that
were quite extensive, so they're not in the 1.4.x branch, but it'll be fixed
in dbus 1.5.6. We might backport that change to 1.4.x for Debian once it has
had some testing.
