ibus-tegaki crashes iBus on Ubuntu Oneiric

[dreamon]

I am using Tegaki with iBus on a fresh install of Ubuntu 11.10 Oneiric (32 bit, US English) on my Samsung Anynet N130 netbook (Intel Atom, 1GB RAM) running the Xubuntu (XFCE) desktop. I have three input methods installed: "Chinese - Pinyin", "Japanese - Anthy" and "Other - tegaki". Tegaki frequently crashes iBus, requiring the user to restart it. This does not happen when running the same version of ibus-tegaki on Natty, although I am using GNOME (Classic) on a 64 bit architecture there.

Steps to reproduce:
1. Set cursor to a text box, activate iBus via Ctrl + Space
2. Switch through input methods using Alt + Shift or the iBus tray icon

Expected result: Tegaki's drawing pad should open, allowing me to draw a character. I should then be able to select another input method, with Tegaki's drawing pad closing automatically.

What happened instead: When activating Tegaki, iBus crashes. Sometimes Tegaki actually starts and shows the drawing pad, but then either Tegaki's drawing pad remains open or iBus crashes when selecting another input method. Crashes are more frequent when using keyboard shortcuts (Alt + Shift).

I believe that key shortcut function is broken between ibus-libs-1.3.99.20110408-2 and ibus-libs-1.3.99.20110419-7.

I can change my input method as I set with shortcut key while I'm using ibus-libs-1.3.99.20110408-2.

But When I'm using ibus-libs-1.3.99.20110419-7, pressing shortcut key crashes ibus or ibus do not work anything.

[fujiwara (fujiwara-redhat-bugs)]

OK, I could reproduce this problem.

The workaround is:
1. Run 'ibus-setup' command
2. Enable "Use system keyboard layout" in "Advanced" tab

Then the problem is no longer happened.

OK, I see the default layout is failed.

Thank you guys. Good luck to you :-)

After playing around a little more and googling for the terminal error message, i found that this is actually related to a bug in ibus itself. i had unchecked "use system keyboard layout" in the "advanced" tab, but this caused ibus to crash when switching to ibus-tegaki. after activating the option, ibus now stays active and does not crash when performing the steps above. so i will add ibus to the list of affected projects.

other than that, tegaki still does not behave quite as expected. after switching away from ibus-tegaki to another input method, tegaki's drawing pad still remains open. this is not intended (it does not happen on other platforms running the same version of ibus-tegaki) and it's a bit of a nuisance. it may be a good idea to have a look at how ibus-tegaki and the current version of ibus interact to find the root of the problem.

[dreamon (dreamon)]

Seems like the hotkey issue has been fixed on Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=718453 I'll close this bug report as soon as I receive an update for iBus which fixes the problem.

[Ikuya Awashiro (ikuya-fruitsbasket)]

I cannot reproduce on Ubuntu Precise.
This issue must fix on new IBus.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
