Created attachment 177139 [details] Debug log Kdenlive 24.12.0 from Debian repositories always crashes on startup. This is the lines I think are important from the debug log: plugin not available: "timewarp" unsupported effect in group "frei0r.alpha0ps_alpha0ps" : "/usr/share/kdenlive/effect-templates/secondary_color_correction_v2.xml" [New Thread 0x7fff2e7fc6c0 (LWP 6757)] [New Thread 0x7fff2dbfb6c0 (LWP 6758)] qrc:/qml/kdenliveclipmonitor.qml: module "org.kde.desktop" is not installed Thread 1 "kdenlive" received signal SIGSEGV, Segmentation fault. 0x00007ffff47d48a8 in QObject::doSetProperty(char const*, QVariant const*, QVariant*) () from /lib/x86_64-linux-gnu/libQt6Core.so.6 (gdb) The appimage version works fine.
Thank you for reporting. If the AppImage is working then it’s a packaging issue. Kdenlive team cannot influence the packager. Please contact the Debian packager team for solve the issue. It seems some xml file is not proper packed ("frei0r.alpha0ps_alpha0ps" : "/usr/share/kdenlive/effect-templates/secondary_color_correction_v2.xml")
