Rhythmbox "blocks" pendrives from mounting

This new bug is being reported as asked in https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/555262

* If Rhythmbox is running and you plug a pendrive on a USB port, the pendrive doesn't get automounted, nor is available for mounting manually (it doesn't even get a device in /dev/)
This shows up in dmesg:

[ 2749.430086] usb 2-4: USB disconnect, address 16

Despite the message in 2749.430086, the pendrive is still plugged on the USB port.

If you close Rhythmbox and then plug the pendrive, it works just fine.

* If you open Rhythmbox with the pendrive plugged and correctly mounted, it takes a lot to start.

I'm using Ubuntu Lucid Lynx, rhythmbox 0.12.8-0ubuntu1. I'm sure the problem is not the pendrive, as I tried with 2 different brands and sizes and the same thing happened. If you need any other information do not hesitate to ask.
