437292 - 'Set as desktop background' not working in Ubuntu 8.04 and Fedora 8

Status: RESOLVED DUPLICATE of bug 421977

(Firefox :: Shell Integration, defect)

Description

[Daniel Holbert [:dholbert]]

Steps to reproduce:
1. Load an image in Firefox 3, e.g. http://www.mozilla.com/img/firefox-title.png
2. Right-click image, and choose "Set As Desktop Background..."
3. Leave default values in the dialog that appears, and click "Set Desktop Background".

EXPECTED BEHAVIOR:  Dialog disappears, and background changes.
ACTUAL BEHAVIOR:  Dialog stays there, and background remains unchanged.

I'm testing using FF3rc1 on Ubuntu 8.04.

In IRC, walters confirmed this bug, using Fedora 8 and a recent Firefox trunk build.

When I try this in a debug build, I get this error message right when the "Set Desktop Background" dialog appears:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIShellService.desktopBackgroundColor]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://browser/content/setDesktopBackground.js :: anonymous :: line 56"  data: no]

sorry, ignore the "When I try this in a debug build" -- I get the error message in optimized builds as well.  (in the JS Error Console)

Additionally, the "Preview" in the Set Desktop Background dialog just shows a blank gray screen on the tiny monitor.

Setting desktop background seems to work with my own x86_64 build on
64bit Fedora 7/Gnome .

FWIW, my libgnome2-0 package (in Ubuntu 8.04) is 2.22.0-0ubuntu1

I guess it's bug 421977

Try running:
gconftool-2  /desktop/gnome/background/primary_color --type=string --set "#f00" 

Then you should be able to change the background.

Yup, that does indeed fix it.

The original value was "#8f8f4a4a1c1c".  And if I restore that value, then setting background breaks again.
