I didn't do anything related to scim (for what I know). After logging as a normal user, I saw the "crashed application" icon, and it was about scim-bridge.

Seems to be like bugs 338217: I renamed ~/.scim/ and reinstalled scim (1.4.9-1ubuntu2) and scim doesn't crash anymore. But my previous configuration is lost (of course).
Here is the previous content of my .scim/, configured for chinese (pinyin).

If I recall correctly, some packages for the chinese support where uninstaled during the upgrade from Jaunty to Karmic.
Now I can't choose pinyin in scim because the scim-pinyin packale is not installed.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug report is public and visible to everyone but I noticed that it has an attachment named 'CoreDump.gz'. It is possible that this contains sensitive information so I've set it back to private.

[Olivier Jeulin (olivierjln)]

Thanks for your concern.
No application with sensitive data (email reader, personnal file, IM, ...) was loaded between the opening of the session and the generation of the core dump. I also used "od -a" + "grep" to check for sensitive data (password, names), and I read the whole file. There is nothing in it that I consider sensitive (there's a user name, but that's OK).
