To reproduce this: 1. Make sure your environment is configured so that Qt4 uses scim-bridge IM 2. go too http://bugs.kde.org/wizard.cgi using konqueror4 3. After one or a few steps in the wizard konqueror will crach with the above backtrace. This hapens att other places as well, plasma have crached with simelar backtrace when browsing for downloadable wallpapers in the configuration.
Could you try app-i18n/scim-bridge-0.4.15-r1? it is fixed qt4 issue by upstream.
I still have this problem with scim-bridge-0.4.15-r1
Would you mind testing this for kde 4.1.2? thanks
Yes, it is still a problem in kde 4.1.2. I haven't seen this in any other program then konqueror for a while. I currecnty need to work around bug #237018 and bug #216127 to get scim-bridge to work in Qt4/KDE4.

Ok then it means it is not falut of kde right?
scim-bridge-0.4.15-r3 in cvs. Could you test it?
I don't have this problem with scim-bridge-0.4.15-r3.
