Seems to only crash with Gtk apps, work fine when I start kedit right away. Also
noticed that there are trouble starting Gtk apps such as gnome-terminal and
firefox after it crashed.

I couldn't reproduce this at all.
It seems like more information is required.

Did you really press "ctrl+shift"?
The following line seems like you pressed trigger hot key.
#1  0x080547d5 in ScimBridgeAgentImpl::filter_hotkeys (this=0x97cecf0, 
    imcontext=0x99d6960, key_event=@0x9a61144) at scim-bridge-agent.cpp:614

Did you use "shared-imengine" mode, or "nonshared-imengine" mode?
It might have something to do with this problem.

Judging from #0 in the debug output, the "factory" must be NULL.
Is this true? Please check that later.

RE: Comment#3
Ryo-san,
You are right, ScimBridgeAgentIMContextImpl::set_enabled looks like coming 
through from hotkey triggering. I have tried to reproduce the bug again  and 
came up with new bt. Hope this is better. I will try to figure out if there is 
another bug related with the previous bt.

I reproduce with nonshared-imengine mode and for <the "factory" must be NULL> 
comment, I think it is more related to the previous trace, hopefully this is 
better.

Thanks and have a nice day. :)

Ryo-san, 
Thanks for pointing out my mistake, new bug 199078 has been created for the 
inital bt.

Could you try again with scim-0.2.5?

Fixed in current scim-bridge afaict.

I did not able to reproduce this bug. Closing it. If bug found again, please
reopen this bug.
