This is probably because the xpra server will set the following
environment variables to try to disable all input methods:
DISABLE_IMSETTINGS=true
GTK_IM_MODULE=xim
QT_IM_MODULE=xim
IMSETTINGS_MODULE=none
XMODIFIERS=""

You may want to remove this code, or change those values back to what
they should be (whatever that is) before starting your application. Does
that help?
That was done because input methods were found to interfere with
keyboard input more often than not (doesn't it need dbus?), at least for
western keyboard layouts that I normally use.
I'll have to admit that I am a bit confused by the number of ways there
are to configure those input methods in X11 / GTK / QT /.., and since I
don't use or need them I prefer to have it completely disabled.
Since this is probably not the right thing to do in all cases, we can
improve this and at least add an option to let the user choose.
I'll need a bit help in doing that though.

If that does not help you, can you tell us how you configured ibus?
How it is meant to work in your use case?

Cheers
Antoine
