gtk-icon-theme error

Hi all,
I'm using JWM and PCManFM on my Debian system. When I click on PCManFM, I get the following error:

GTK+ icon them is not properly set

This usually means you don't have an XSETTINGS manager running. Desktop environment like GNOME or XFCE automatically execute their XSETTING managers like gnome-settings-daemon or xfce-mcs-manager.

If you don't use these desktop environments, you have two choices:
1. run an XSETTINGS manager, or
2. simply specify an icon theme in ~/.gtkrc-2.0. For ex: to use the Tango ion theme andd a line: gtk-icon-theme-name="Tango" in your ~/.gtkrc-2.0. (create it if no such file)

But there is no error when I open Nautilus.

There is no .gtkrc* file in my home directory. There is only a 'im-multipress.conf' file in the /etc/gtk-2.0/. There are many gtkrc files in /etc/gtk/ but i didnot understand them and there was no mention of gtk-icon-theme-name in them anyway.

As suggested in the error msg, I also tried creating ~/.gtkrc-2.0 and put the line: gtk-icon-theme-name="Tango" there. Did you say dumb? :)

What can I try? A link would also be appreciated.

Cheers,
SV
