Status: RESOLVED WORKSFORME

(Core :: Networking: HTTP, defect)

Description

[Dan]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050926 MultiZilla/1.8.1.0n SeaMonkey/1.1a
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050926 MultiZilla/1.8.1.0n SeaMonkey/1.1a

Seamonkey has trouble displaying the gifs on the front page. It opens fine with
1.7.x based browsers and firefox 1.5beta. Saving the file in seamonkey causes
photoshop not to recognize the file format, but saving in firefox 1.5beta allows
all image apps to open the local gif file, including seamonkey.

Reproducible: Always

Steps to Reproduce:
1. go to http://www.zzounds.com/
2.
3.

Actual Results:  
gifs on front page don't load such as
http://media.zzounds.com/media/promos/FEN134602-d299fd556c9d7929f76d7fead6f104e8.gif

Expected Results:  
render the gifs correctly

just an update, I erred in saving the file with seamonkey. saving the file in
seamonkey before the fancy error page shows up (pressing stop milliseconds
before it shows up) shows that the file is normal and can be viewed with any
image application, including seamonkey

I get this error in Firefox trunk:

"The page you are trying to view cannot be shown because it uses an invalid or
unsupported form of compression. Please contact the website owners to inform
them of this problem."

Opera and IE handle it OK, though.

Reproducible with SeaMonkey/20050917 but WFM with SeaMonkey/20050915 (and
SeaMonkey 1.0a).

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.9a1) Gecko/20050919 SeaMonkey/1.1a
http://media.zzounds.com/media/promos/rolmicrocube120x50-7ddaca1b9bc2860b07fa8b9ccd0d0dbd.gif

This is one of the images not displayed on the main page.
If I open the link above directly, the gif should be loaded, but Seamonkey gives
me an error message: 

Cannot Complete Request

The page you are trying to view cannot be shown because it uses an invalid or
unsupported form of compression. Please contact the website owners to inform
them of this problem.

Additional information about this problem or error is currently unavailable.


Page Info (Ctrl+I) tells me I'm looking at 

Page Load Error:
Address:     http://media.zzounds.com/media/promos/rolm ...[cut]... .gif
Type:        application/xhtml+xml
Render Mode: Standards compliance mode
Encoding:    UTF-8

Firefox 1.0.5 renders the image, and Page Info tells:
rolmicrocube120x50- ...[cut]... .gif (GIF Image, 102x50 pixels):
Type:        image/gif
Render Mode: Quirks mode
Encoding:    ISO-8859-1


I don't have LiveHTTPHeaders installed, but looking at PageInfo it seems the
wrong MIME type is served for these images.
Don't know why rendering a gif in a new tab has different encodings or Render
Modes.

maybe: Show a useful error message if a page claims to be compressed and isn't.

Bug 184144 Blank page and no error message a page with encoding gzip is not
compressed

I don't know if the images are compressed or not, I'm just guessing.

Sorry, my development HDD died, and I have ordered a new one, but I won't be
able to look into anything before I have my environment set up again.

Is this an issue in a current build?
