Thunderbird 2.0
Xubuntu 9.10 Beta

I'm using a theme with dark menus, and this theme demonstrates that several widgets in Thunderbird are not themed properly (either they don't use the good gtk widget's theme or they don't respect the gtkrc's colors).

The screenshot here demonstrates the 4 issues: http://launchpadlibrarian.net/32940044/Capture-6.png

Reproducible: Always

Steps to Reproduce:
1. Install thunderbird 2.0 in your favourite linux distibution (by default in Xubuntu).
2. Use a theme with a dark menu (Albatross will work for that purpose, installed by default in Xubuntu 9.10 - any other dark theme has this problem, dust burnt for instance)
Actual Results:
Open the preferences dialog and notice that in some tabs (for instance the display one), the background color if captions in groupboxes is dark. It uses the bg[NORMAL] colour of GtkMenu instead of using the one of GtkLabel.

Open any menu and notice that the menu separators are not themed at all, and that insensitive menu entries don't use the fg[INSENSITIVE] colour of GtkMenu or GtkMenuItem (it's possible that colours for the other states - NORMAL, ACTIVE, PRELIGHT, SELECTED - are not fetched properly either).

Notice the GtkTreeViewColumns (Subject, Sender, Date, etc.) are not themed at all

Expected Results:
I expect the treeview columns to be themed, the menu to use the theme's colours properly, and the captions in the preferences dialog to be drawn with normal label colours.

This happens with the default Thunderbird theme, with the version uploaded in Ubuntu Jaunty AND Karmic, on several machines, with no plugins or hacked files or whatever, with pretty much every theme with dark menus.
