            Blocks: 617282
    Classification: Fedora
    Target Release: ---

Description of problem:
not testing other desktops but the icon at the systray isn't reflected as
expected when activating ibus on Xfce.

Version-Release number of selected component (if applicable):
ibus-1.3.99.20101202-5.fc15.x86_64
xfce4-session-engines-4.7.3-1.fc15.x86_64
xfce4-session-4.7.3-1.fc15.x86_64
xfce-utils-4.7.4-1.fc15.x86_64

How reproducible:
always

Steps to Reproduce:
1.log into the xfce desktop
2.run any applications
3.press ctrl+space or anything to start typing something through ibus

Actual results:
input is ok. but the icon at the systray still keeps the keyboard icon.

Expected results:
the engine's icon should appears.

Additional info:
no changes behavior with setting GTK_IM_MODULE=ibus explicitly. this is
reproducible on both X and GTK+ applications.
the icon works on GNOME. so this may be Xfce specific issue. not tried KDE and
LXDE and more though.
