Whenever I use the close button of kdenlive (top right x) the application crashes and my plasma shows me "kdenlive closed unexpectedly" with "Executable: kdenlive PID: 9340 Signal: Segmentation fault (11)" Running the latest KDE Neon 5.9
I can confirm the exact same behaviour with kdenlive 17.03.80 running on OpenSUSE Tumbleweed, KDE Frameworks 5.33, QT 5.7.1. This is the output when started from the console: (...) QXcbConnection: XCB error: 8 (BadMatch), sequence: 20095, resource id: 75498013, major code: 130 (Unknown), minor code: 3 [swscaler @ 0x7fa10c1dc060] Warning: data is not aligned! This can lead to a speedloss KCrash: Application 'kdenlive' crashing... KCrash: Attempting to start /usr/lib64/libexec/drkonqi from kdeinit sock_file=/run/user/1000/kdeinit5__0 [1]+ Stopped kdenlive
Could you add a backtrace for the crash? For more information, please see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
Dear Christoph, I reproduced the crash and generated a backtrace, using KDE Crash handler. See attachment.
