Version: (using KDE KDE 3.5.5) Installed from: Ubuntu Packages OS: Linux Pressing a valid shortcut key, such as "R" for "reply," while SCIM is in Japanese input mode causes an immediate crash of KMail. The error log reports SCIM-related errors. This bug is nearly 100% reproducible, and has been observed in every KDE version including 3.5.6, and on a variety of distributions including openSUSE and Ubuntu.
Please provide a backtrace. Could this be the following bug: https://bugzilla.novell.com/show_bug.cgi?id=206547 ?
Please also provide a description of how to set up (or give a good link) SCIM for Japanese, since trying to reproduce the bug is going to be difficult otherwise.
Installing SCIM for Japanese is done in KDE simply by adding Japanese as a supported language. (In KDE 3.5.6 this is done in the Control Center under Regional & Accessibility | Country/Region & Language.) The SCIM and associated programs, including Anthy for Japanese input, should be installed automatically (in distros that have Japanese support, such as (K)Ubuntu or openSUSE or Fedora). Then choose Settings | SCIM input method setup. The default keyboard shortcut for switching to Japanese mode is Ctrl+Space. Now, in KMail, enable Japanese input mode. Then press the "R" key to reply to a message. I did that just now, with the following result: (no debugging symbols found) Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

This backtrace looks very much like the backtrace from the SuSE bugreport at https://bugzilla.novell.com/show_bug.cgi?id=206547. It is not a KDE bug, but a SCIM bug, which is a third party app or library. SuSE has updated packages at http://software.opensuse.org/download/M17N/. I don't know about Ubuntu. That report says any app crashes when opening a second mainwindow. The report specially tells how to reproduce this for Kopete. If my assumptions here are wrong, please reopen this report.
I can't reproduce it in Gnome applications (e.g., Evolution or Liferea). Isn't it a bug in interaction between SCIM and KDE? If SCIM is broken in KDE, does KDE have a non-broken means for Japanese input? wataru
To dispel any misunderstanding and controversy, I am very much pro-KDE, and consider the latest KMail to be the greatest email program for any platform available today. You are quite possibly correct that the fault is entirely with SCIM. I see that Mike Fabian over at Novell has uploaded a possible fix for a similar problem, as you have noted. But that fix is only for SUSE. Will it need to be made separately for each distribution? Is there nothing that can be done on the KDE end to fix it? If this problem is completely KDE-independent, you may close the bug and I'll try to find a fix elsewhere.
I think the problem is KDE independent. SCIM works with all Qt apps, so this is a problem for all Qt applications, including KDE. I am not sure however. I am not sure if this is the same problem, but you should try the workarounds at http://forum.skype.com/index.php?showtopic=64211.
Thomas, thanks for looking into this. You are probably correct that it is a SCIM + Qt issue, not the fault of KDE itself. I'll close the bug and look elsewhere. I'm not sure how the Skype workaround can be used with KMail. Can you explain? wataru
I'm marking as Resolved, due to the lack of clear dependence on KDE. The issue itself remains, however.
I have now updated my openSUSE installation with the revised SCIM and related files. This appears to have fixed the problem, at least for openSUSE. Thanks, Thomas, for pointing out the fix. wataru
