Description Warren Togami 2009-03-30 19:47:48 UTC

gtk2-2.16.0-1.fc11.x86_64
gedit-2.26.0-1.fc11.x86_64
ibus-1.1.0.20090311-3.fc11.x86_64
ibus-hangul-1.1.0.20090328-1.fc11.x86_64

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.

Comment 1 Peng Huang 2009-03-31 04:52:02 UTC

Please update ibus to 1.1.0.2009331-1, and try again. Thanks

Comment 2 Warren Togami 2009-04-02 05:03:41 UTC

Still broken.

Comment 3 Warren Togami 2009-04-02 21:35:39 UTC

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.

Comment 4 Jens Petersen 2009-04-04 03:57:22 UTC

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.)

Comment 5 Warren Togami 2009-04-06 20:04:02 UTC

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.

Comment 6 Warren Togami 2009-04-06 21:10:23 UTC

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.

Comment 7 Peng Huang 2009-04-07 04:43:00 UTC

I think it is a bug in ibus. I fixed in ibus-1_1_0_20090407-1_fc11. Please test it.
