Issue running firefox built from source (on Ubuntu 9.10)

The title of the question sums it up pretty well. I've downloaded the source for firefox 3.6 and built it (no errors), but when I try to run it, I get a warning that says:

(firefox-bin:2857): GLib-WARNING **: g_set_prgname() called multiple times

I'm not sure what to try now. Any suggestions? Or even a 开发者_StackOverflowbetter place to ask this question?

*EDIT - It's not that I only get a warning, that wouldn't bother me. The problem is that the warning is the only thing that ever happens (no firefox windows show up or anything). When I run it from the terminal, that warning shows up twice and then nothing else happens (it just hangs and I have to Ctrl-C it).

Bug in Glib introduced while trying to fix https://bugzilla.gnome.org/show_bug.cgi?id=563627 and, as discussed in that bug, later backed out because of the issue you're seeing. The warning will go away once you get a newer version of Glib.

Quick comments:

1. It's a warning, not an error. This is not a problem but looks like the library wanted to be used differently. So why worry?

2. Why did you build it from source? If you want newer packages, I usuaully start with Debian sources and turn those into local packages -- as this incorporates whatever the package maintainers deemed worthy and will be closer to the package you will get at the next Ubuntu upgrade.
