Binary package hint: devicekit-disks

We will be comparing load time for a disk (USB or SD) in Jaunty vs. Karmic to demonstrate that in karmic devicekit-disks takes a long time to enumerate disk before mounting it to the desktop and displaying its contents.

Steps to reproduce:

Need Materials: Jaunty CD, Karmic CD, stopwatch. it is good to gave a large usb drive (160GB, 1TB etc) and a smaller usb drive (8GB, 16GB) and make sure they are full of files,.

1) In Jaunty, plug in a 8GB and time how long it takes to mount & show contents.
2) In Karmic, plug in a 8GB and time how long it takes to mount & show contents.
3) In Jaunty, plug in a 1TB and time how long it takes to mount & show contents.
4) In Karmic, plug in a 1TB and time how long it takes to mount & show contents.

Result: Mounting a disk in karmic takes much longer than in jaunty. In karmic, the larger the drive the longer the wait time before being able to see the contents. During this wait, there is no progress bar displayed. If a user clicks on the drive again to have it mount, they will get an unusual (un-human-friendly) error. See attachment for error.

Expected: Newer version of ubuntu should improve performance instead of making basic functionality slower and introduce new errors.
