I noticed today that my Taiwan trip gallery shows up empty. A followup shows that the files exist on my system… although a search also reveals several Gallery exploits out there, including a recently found remote exploit. A cursory glance through the logs doesn’t turn up anything fishy (tac | grep gallery | grep HTTP_ to check if the exploit had been run)
(Update: ok, looks like a corrupted photo.dat. After poking around a bit, I figured out how it works. Luckily, only the last photo entry was truncated, and I fixed it by copying the missing data from the photo before it)
