Looks like I’ve found a bug in Kindle DX PDF viewer: any time I open the second page of this PDF file Kindle DX would go into quick reboot. When it comes out of the reboot all of the items are gone from the home screen. To get them back I needed to create some dummy text file to force folder rescan.
It would be nice if someone could try to reproduce this crash and confirm that this problem is not specific to my Kindle. A word of warning though – although there seemed to be no lasting damage to my device and all my files were intact as well this kind of crashes (I would guess a buffer overflow or NULL pointer dereference) have potential for damaging the data. So if you feel like reproducing this bug do it at your own risk.
I’ll also follow up on this issue with Amazon and keep you posted on the progress.
