SOFTWARE VERSIONS
kdenlive 18.11.70
KDE Frameworks Version: 5.48.0
Qt Version: 5.11.1

Comment 1 emohr 2018-10-20 19:20:04 UTC

It seems "No LADSPA plugins were found!" which is probably needed for this effect.
So the installation is not complete.

Please try with the actual Kdenlive AppImage version 18.08.2
Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage

Comment 2 Alexander Potashev 2018-10-21 08:07:46 UTC

After installing the "ladspa" package on Fedora the "No LADSPA plugins were found!" warning does not appear anymore, but kdenlive still crashes in these scenarios.

I prefer to run the latest version of kdenlive built from Git master, 18.08.2 is too old for me.

Comment 4 emohr 2018-10-21 16:29:55 UTC

So with the 18.08.2 version it works?

Be aware: 18.08.2 is released (stable). Branch 18.11.70 (with the latest Beta7 version) is from the timeline_refactoring branch and not stable/released (just for testing purpose).

Comment 5 Vincent PINON 2018-10-21 19:41:36 UTC

Hi Alex, glad to read you're using Kdenlive :)

18.11.70 appears in both master (very similar to 18.08) and refactoring_timeline (which regularly merges master, and maybe will be soon merged into master)

as crash is happening in MLT, what version of limlt6 do you use?
it might also helping to build latest MLT from source (0.6.10 or even git master).

Cheers,

Vincent

Comment 6 Alexander Potashev 2018-11-05 17:45:50 UTC

I didn't try with 18.08.2.

I use mlt-6.10.0-2.fc28 (from Fedora 28 official binary packages).

Should I try and debug "master" or "timeline_refactoring"? Which of these is considered more crash-resilient?

Comment 7 Alexander Potashev 2018-11-05 18:47:46 UTC

I just tried 18.08.2 with MLT 6.10.0 on Archlinux and it doesn't crash. However there may be some difference between distros (Archlinux vs Fedora+compiled kdenlive).

Comment 8 emohr 2018-11-10 13:32:19 UTC

Yes, there are some differences between the distros. This is why you should always try the AppImage.
I close this Bug. If you think we need further investigation reopen it.

Comment 9 Alexander Potashev 2019-04-28 13:09:28 UTC

Does not crash anymore with Kdenlive 19.04 on Archlinux :)

Comment 10 emohr 2019-04-28 17:28:45 UTC

Thanks for the feedback. Glad to hear it works. 

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.
