Version: Version 1.3 Using KDE 4.1.00 (KDE 4.0.99 (4.1 RC1+)) (KDEmod) in ArchLinux (using KDE 4.0.98) Installed from: Compiled From Sources Compiler: gcc 4.3.1 i686 CXXFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer" OS: Linux Using KDE 4.1.00 (KDE 4.0.99 (4.1 RC1+)) (KDEmod) in ArchLinux Installed KDEPIM components: kdepim-akregator kdepim-common kdepim-kaddressbook kdepim-kmail kdepim-kontact kdepim-korganizer kdepim-ktimetracker kdepim-wizards Steps to reproduce: - (If you want, delete your ".kde/share/config/kontactrc" to revert to defaults) - Start Kontact, go to Settings, disable the KMail component from the sidebar, click OK. - Close Kontact - Start Kontact, go to Settings. If opening the Settings window doesn't crash the application, clicking anywhere in the sidebar will do the crash. From this moment, Kontact settings cannot be opened until you delete the kontactrc file and revert to default. KMail settings will open OK. Here is the backtrace: Aplicación: Kontact (kontact), señal SIGABRT [Thread debugging using libthread_db enabled] [New Thread 0xb4e5f700 (LWP 16455)] [KCrash handler] #6 0xb7f9e424 in

Still reproducible here using: Qt: 4.4.3 + qt-copy-patches-889120 KDE: 4.1.87 (KDE 4.1.87 (KDE 4.2 >= 20090101)) kdelibs svn rev. 905454 / kdebase svn rev. 905455 kdepim svn rev. 905565 on ArchLinux x86_64 - Kernel 2.6.27.10
To reproduce the crash: after you have disabled the Mail component, accepted the dialog: in the Settings click any of the disabled KMail items. Kontact will crash (I suppose this is because the item you selected is trying to access to KMail configuration and as there is not a KMail instance (the KMail component is disabled))
I can't reproduce this exactly here using: Qt: 4.5.0-rc1 KDE: 4.2.63 (KDE 4.2.63 (KDE 4.3 >= 20090212)) kdelibs svn rev. 927117 / kdebase svn rev. 927117 kdepim svn rev. 928042 on ArchLinux i686 - Kernel 2.6.28.4
Amazingly, this bug still exists in KDE 4.4.2!
