I started getting these on the machine that I upgraded from maverick to
natty with the "new & improved" nvidia-96 driver. Have a look at:
[Xorg.log flooded with specific Xalloc warning message about 0 size memory ]
[*Lots* of DEBUG messages from GsmDBusClient ]

Also, on that same system; when it was running 10.10 my logitec wireless
mouse was doing just as you describe. It's an old:
046d:c510 Logitech, Inc. Cordless Mouse

However I had the same issues on a new M505 mouse as well. Oddly enough,
it was only on that one system, which is a mirror of another system
(hardware and software).

If I recall correctly, it started when I experimented with HIDPoint
( but can't say
for sure.

In any event, the mouse is working fine now following the upgrade to
natty. Even booting into the old 10.10 kernel (2.6.35-30-generic) works
fine. *And* I installed 10.04 on the other day on a second drive in the
same machine for testing, and the mouse works fine there as well. So in
my case the issue was neither the hardware or the kernel etc., and had
to have been a simple configuration issue.

You might try adding another user account & see if the mouse acts the
same in the other account. If it does then start looking for a
system-wide config issue (xorg.conf etc). Good luck as I know how
frustrating a wonky mouse can be.
