No more JPEG images in XFCE (snif)

[John Coppens]

Hello people.

At some random point in time, XFCE stopped showing jpegs. Background
image in jpg don't show anymore, and Thunar crashes when trying to open
a jpg. PNGs etc work normally.

I've found quite a few references to similar problems, but libjpeg
seems ok, and other solutions don't seem to work either.

Where should I start looking, and what do I look for?

Thanks,
John
