unexpected identifier `gtk-alternative-button-order' ??

[Eduard Polyakov <ed_po netvision net il>]

Hi every one!
I'm a newbie, using Fedora Core 4, KDE.
I was  unsuccessfully trying to install ethereal-0.10.11-2 via rpm and 
eventually gave up and installed it from source.
I manage to launch ethereal but it gives an error during the launching 
process:

/home/ed/.kde/share/config/gtkrc:37: error: unexpected identifier 
`gtk-alternative-button-order', expected keyword - e.g. `style'

It also dosn't work properly, when i try to choose the interface for 
sniffing the program just closing up and gives me another error.
Here is my ethereal --v :
Compiled with GTK+ 1.2.10, with GLib 1.2.10, with libpcap 0.9.2,
with libz 1.2.3, with libpcre 5.0, with Net-SNMP 5.2.1, without ADNS.
Running with libpcap version 0.9.2 on Linux 2.6.11-1.1369_FC4.

What am i doing wrong?
Thanks in advance!
