Cannot use scim in certain circumstances

Hello,
I'm now testing Mandriva 2010.1 RC2 install.
As the subject suggests, I cannot use scim in the following circumstances:
Icewm: cannot use scim to input anything at all.
LXDE: cannot use scim in OO.o and urxvt.
KDE: cannot use scim in OO.o and urxvt if autologin disabled.
Could you try if any of the above problem is replicable?

Thanks,

You-Cheng Hsieh
