Corrupted JPEG images

[automatedbugreportingfacility]

This is a regression. The images on page 2 and 4 are corrupted.

This bug occurs only in Nightly. This bug doesn't manifest with the pdf viewer built in the browser (which is at 1.1.165, and as such should be affected, because the commit triggering the bug was added in 1.1.148), but it does manifest when the development version is installed.
