Created attachment 119584 [details] gdb terminal output SUMMARY After having created a project with Kdenlive 18.12.1b-x86_64.appimage very successfully I can not get to edit it or any other material anymore. All I did inbetween was starting and closing the 19.04-Appimage and changing the library. STEPS TO REPRODUCE 1. Opening a clip or a project 2. Pressing play on the clip monitor or on the project monitor OBSERVED RESULT Kdenlive freezes. EXPECTED RESULT Kdenlive plays the clip or project. SOFTWARE/OS VERSIONS Linux Mint 18.3. Cinnamon 64-bit KDE Frameworks Version: 5.53.0 Qt Version: 5.11.2 MLT version 6.13.0 ADDITIONAL INFORMATION I suspect it could have to do with having used the 19.04-Appimage which uses MLT version 6.15.0 Also the 19.04-Appimage is not able to play any clip or project. It just freezes.
Seems the same solution like in bug https://bugs.kde.org/show_bug.cgi?id=402593.
Could you solve the issue by deleting "kdenliverc"? If not delete "kdenlive-appimagerc" as well.
Hi emohr, thanks for getting back on this. Before I red your suggestion I fiddled around with the cached files. I just deleted all that I found in USERNAME/.local/share/kdenlive and in USERNAME/kdenlive and now I can play and edit the 18.12.-project in 19.04 with no problem.
And I can of course also still and again edit it with Kdenlive 18.12
Thanks for the feedback. I update the documentation here: https://community.kde.org/Kdenlive/Configuration#GNU.2FLinux and here: https://userbase.kde.org/Kdenlive/Manual/Windows_Issues . We close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
