Status: RESOLVED DUPLICATE of bug 514033

(Core :: Graphics: ImageLib, defect)

Description

[Alexander Shishkin]

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; en-US; rv:2.0b2pre) Gecko/20100716 Minefield/4.0b2pre
Build Identifier: Mozilla/5.0 (X11; Linux x86_64; en-US; rv:2.0b2pre) Gecko/20100716 Minefield/4.0b2pre

When trying to open http://busybox.net/~vda/blackhole_1d.png in minefield, I see the URL text instead of the picture. The content type reported by the server seems to be correct. If I save the picture locally and then open it, the outcome is the same.

Reproducible: Always

Steps to Reproduce:
1. Enter http://busybox.net/~vda/blackhole_1d.png in the address bar.
Actual Results:  
The picture is displayed.

Expected Results:  
Picture's URL is displayed instead.

I'm using nightly snapshots of firefox on x86_64 linux (debian unstable).

IE6 also not opening this picture,
 google chrome, opera, safari and firefox 3.5.9 opening it without problems

libpng12 users in linux also display the picture just fine.

Why not do that, then, instead of just hoping someone will?

Range for going from showing to blank: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ff3496b1f6c7&tochange=bf0fdec8f43b

Looks like the decode on draw landing.

Comment 7

[Bobby Holley (:bholley)]

My guess is that this is the result of stricter error handling. See bug 514033...

Comment 8

[Boris Zbarsky [:bzbarsky]]

And going from blank to alt text happened in http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=bf0fdec8f43b&tochange=912c6ae3b70c which corresponds to decode-on-draw being disabled.

I'd mark this dependent on bug 514033, but the deps don't work out that way.... :(

Shouldn't we just mark this as a duplicate of bug 514033?

Comment 11

[Joe Drew (not getting mail)]

blocking- until comment 10 is resolved. Please renom if this isn't a duplicate.

The image displays in a recently nightly, so I'm going to say it is a duplicate of  bug 514033.
