Fujiwara-san, could you apply this patch:
when you update ibus package in rawhide next time?
The patch should fix this bug.

Please note that the patch disables surrounding-text by default and you will need to add --enable-surrounding-text to

Comment 2 fujiwara 2010-11-21 23:03:40 EST
Integrated the fix into rawhide.

I thought to remove IBUS_CAP_SURROUNDING_TEXT in ibusimcontext->caps by default and add some APIs.
But there are timing problems between gtk client's focus-in and loading bus engineproxy and will need several dbus APIs.
So now I think customizing IBUS_CAP_SURROUNDING_TEXT may not help to reduce the resources.

I will integrate the patch into f14 later.
