349838 - [Linux] Blank or partial display of stand-alone png images

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

I've had no luck getting the Linux trunk Firefox to display stand-alone png (Portable Network Graphics) images: either the screen is completely blank or only the top of the image is shown. 

All the same, Firefox has no problem showing the same image inline on a page; it's only when the pgn image is to be displayed separately that the bug appears.

Reproducibility: 100 % blank images when tested against an in-house web server. With a slower connection, the images will be more or less cut off.

How to reproduce:
1) Open the attached png image.

Desired outcome: Firefox should display the image in full.
Actual outcome: Firefox either does not display the image at all, or it displays a blank page.

This looks like a regression, since Firefox 2.0 Beta 1 doesn't have the same problem.

Even for inline images sometimes this effect occurs (not completely visible or black replaced by white). See the first image "The Gamma function along part of the real axis" on:
http://en.wikipedia.org/wiki/Gamma_function
Its completely white. The other images show up correctly.
