SUMMARY On the latest Appimage, version 24.12.0-x86_64 I'm not able to start the program as I get the following error: Could not create video preview window. There is something wrong with your Kdenlive install or your driver settings, please fix it. Two instances of this error pop up immediately and after clicking one away the program closes with a Segmentation fault. STEPS TO REPRODUCE 1. Download latest Appimage 2. Set execute bit 3. Start Appimage OBSERVED RESULT Two error popups and segfault EXPECTED RESULT No errors and no segfault SOFTWARE/OS VERSIONS Linux: Debian 12 x86_64 ADDITIONAL INFORMATION I have reset the `.config/kdenlive-appimagerc` settings file and still get the same result. This was in an attempt to confirm https://bugs.kde.org/show_bug.cgi?id=464181 but am not able to because of this bug.
Beside deleting: "~/.config/kdenlive-appimagerc" Delete "~/.config/kdenliverc" as well More details see here: https://docs.kdenlive.org/en/getting_started/installation.html#configuration-information
This leads to the same 2 error popups and subsequent segfault.
I noticed these lines in dmesg that might be meaningful: [1448025.729081] AppRun.wrapped[1484417]: segfault at 0 ip 00007f3aac624240 sp 00007ffdbc5329c8 error 4 in libmlt++-7.so.7.28.0[7f3aac605000+2b000] likely on CPU 11 (core 6, socket 0) [1448025.729098] Code: 54 24 08 48 89 34 24 ff d0 48 8b 54 24 08 48 8b 34 24 48 83 c4 18 48 89 c7 e9 9c 88 ff ff 66 66 2e 0f 1f 84 00 00 00 00 00 90 <48> 8b 07 48 8d 0d e6 f8 ff ff 48 8b 40 10 48 39 c8 75 0d 48 8b 7f
The crash seems to be happened in MLT (the underlying framework of Kdenlive). Which was the latest Kdenlive AppImage version which were running on your system? Maybe you have to update your system with: sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade
Previously I'd use kdenlive-21.04.2-x86_64.appimage as that was the only one that could connect to alsa. However this now also misbehaves similarly. My Debian 12 system is currently fully up to date.
