Why scim language prompt isn't shown from QT applications?

[Yuri]

I have these scim-related ports installed:
linux-f10-scim-gtk-1.4.7 Smart Common Input Method platform, gtk module, 
(Linux Fedo
linux-f10-scim-libs-1.4.7 Smart Common Input Method libraries (Linux 
Fedora 10)
linux-scim-gtk-fc4-1.4.4_2 Smart Common Input Method platform, gtk 
module, Linux binar
scim-1.4.7_5        Smart Common Input Method platform
scim-bridge-0.4.15_1 Scim-bridge agent (server)
scim-bridge-qt4-0.4.15 Qt4 client for Scim-bridge
scim-input-pad-0.1.2_1 SCIM add-on to input various symbols with 
customisable on-s
scim-table-imengine-0.5.7_4 SCIM table based input method engine
zh-scim-chewing-0.3.3 SCIM chewing Chinese input methods
zh-scim-pinyin-0.5.91_6 SCIM Chinese Smart Pinyin input method
zh-scim-tables-0.5.7_3 SCIM table based Chinese input methods


I have these scim-related processes running:
 1589  ??  Ss     0:00.29 /usr/local/lib/scim-1.0/scim-launcher -d -c 
simple -e all -f socket --no-stay
 1592  ??  Is     0:00.00 /usr/local/lib/scim-1.0/scim-helper-manager
 1593  ??  Ss     0:02.37 /usr/local/lib/scim-1.0/scim-panel-gtk 
--display :0.0 -c socket -d --no-stay

Yet, scim prompt only works from GTK apps windows, not from QT apps like 
opera and konqueror.

Do you have scim working from QT apps? Do I miss some ports? Or some 
processes aren't running?

Thanks,
Yuri
