This bug is a major PITA. Today I had to plug a pendrive here at work
on my Ubuntu 10.04 and, since udev is turned off to avoid this bug, it
was not automatically mounted. I started udev and then plugged the
pendrive, and this time it was properly automounted, but the events
storm started all over again. I had to turn the service off right
after I copied the files.

Regards,

Andre
