iPod iPod space issue

[macaleph]

iTunes (10.5) shows in its barchart that my iPod 2G nano is using 7.4GB for Audio (with 0.06GB for Other and 0.04GB Free).

In Music, I'm told I'm using 5.31GB for 824 songs and in Podcasts, 454MB for 35 podcasts.

Since 5.31 + 0.454 doesn't come anywhere near 7.4, I'm wondering what could account for the gap.

Do you have any audiobooks?

I don't have any audiobooks. The only two sections under my iPod on the left iTunes pane are Music and Podcasts.

I'm getting the same thing with my iPhone. I think it is a bug in iTunes. I have 8.9 GB free, but iTunes shows I have 7.9 GB free.
