if I start kbackup from gui, I get no response. If I start it from the command line, I get this message: kbackup: symbol lookup error: kbackup: undefined symbol: _ZN3KIO8UDSEntryaSEOS0_ version: 1.0.2-2.9 openSUSE Tumbleweed, KDE:Extra repo
problem persists after update to 1.0.2-2.10
It seems you do not have the KF5 5.44 version libraries installed. The missing symbols were apparently added in 5.44 in the KIO library: https://api.kde.org/frameworks/kio/html/classKIO_1_1UDSEntry.html#aae30cf07df015ed4c35ca62a0576b818 https://api.kde.org/frameworks/kio/html/classKIO_1_1UDSEntry.html#a2a1823a714b538113444adb3ac0d6d38
