[Bug 1226537] [NEW] System proxy settings doesn't work in Firefox when URL is a numeric IP address

[AZLinux]

Public bug reported:

Description:	Ubuntu 12.04.2 LTS
Release:	12.04
Firefox 12.0

I use a proxy to Internet navigation.

Step to reproduce bug:

1. Configure proxy values in Ubuntu (Network sytem settings). Manual method
2. Configure proxy in Firefox > Use system proxy settings
3. Type URL > www.google.es > Web page works
4. Type numeric URL > 173.194.41.223 (www.google.es) > loading........ Connection timeout!

Notes.

Reading similiar bug #1194841 > Idea!!
remove  /usr/lib/firefox/components/libmozgnome.so

Then all is OK and numeric URL works

Conclusion

In my view, a problem exist between Firefox and Gnome. Firefox doesn't
obtain correctly proxy values from gnome when a numeric URL is typed
