Hello, I found nice workaround, when i try to debug problem with krunner, kscreensaver, etc.. Next steps solve this problem without downgrading to previous version of Qt: 1. Sync abs tree from root 2. Go to /var/abs/extra/kdebase-workspace 3. Edit PKGBUILD and change: -DCMAKE_BUILD_TYPE=Release to -DCMAKE_BUILD_TYPE=Debug 4. Same for /var/abs/extra/kdelibs 5. Build and install both packages with 'pacman -U' After this trick krunner, kscreensaver, and some other components of KDE start working as expected. -- Best regards, Dmitry Korzhevin Tel: +38 (039) 295-0000 Office Phone: +38 (044) 383-14-12 E-mail: dkorzhevin@xxxxxxxxxxxx Jabber ID: dkorzhevin@xxxxxxxxxxxx Skype: dkorzhevin URL: http://lsupport.net Linux Support LLC
