ibus-hangul can cause gtk app to lockup
Last modified: 2009-04-07 00:43:00 EDT
1) Run gedit.
2) Activate ibus-hangul.
3) Type "wkk"
4) Use hotkeys to cycle through all engines, then back to Hangul.
5) Hit Backspace a few times.
6) gedit locks up.
Please update ibus to 18.104.22.1689331-1, and try again. Thanks
There seem to be numerous other ways in which ibus-hangul can cause the entire GTK+ app to lockup. It happened to me a few times by only Alt-Shift cycling through my active engines. Bumping up priority because this is pretty bad.
I can't reproduce exactly - for me when I cycle back to Hangul it just stops working - ie I can only continue to input ascii even though ibus says hangul is activated but the config button is gone from the toolbar. (Additionally I can get next-engine bindings with Alt to work though this is under virt if it matters.)
It seems the most common way to cause the gtk+ app to lockup is if you next-engine cycle from hangul. I can however get the gtk+ app to lockup sometimes when attempting hanja character conversion. Like: wk then press F9.
ibus-hangul, no next-engine switching, just hitting the Hanja button often locks up here.

NOTE: If we cannot fix this before Fedora 11, we need to backout to the pre-Hanja ibus-hangul. It sucks, but the desktop is at least usable.
I think it is a bug in ibus. I fixed in ibus-1_1_0_20090407-1_fc11. Please test it.
