kdenlive crashes on Linux Mint Cinnamon - Aborted (core dumped) - ./nptl/pthread_kill.c: No such file or directory.

[ElijahG]

Hi, I and some other people are having an issue with kdenlive(both stable and experimental versions appimage / flatpak) on Linux Mint Cinnamon (there is a KDE bug report at https://bugs.kde.org/show_bug.cgi?id=462777). Kdenlive crashes after two clicks between any kind of tracks (audio/video) with any kind of effects(gain, fade, etc) in the timeline. The last lines of console output are:

Code: Select all

deleting collapsibleeffectview
terminate called after throwing an instance of 'std::out_of_range'
what(): _Map_base::at
Aborted (core dumped)

Only some specific Linux Mint Cinnamon machines seem to be affected. Kdenlive did't crash when I tried replicating the bug on the same computer but in a different desktop environment (KDE Plasma). So, it seems to me that it's connected to Cinnamon somehow. Strangely enough the issue is also absent when I run Kdenlive with sudo on Linux Mint Cinnamon.

I ran Kdenlive with gdb and got this in the log; I have a feeling it might mean something:

Code: Select all

./nptl/pthread_kill.c: No such file or directory.

The full log:

At this point, I am convinced that the bug doesn't originate from kdenlive itself, but perhaps from Cinnamon.
So, does anyone know what's going on here and how to fix it?

Thanks for reporting that. Reviews on Kdenlive have been very good over the last 2 years, including the last review 2 months ago.
I guess many people are unaffected by the bug.

I also have this problem since recently. Maybe 2-3 months or so.
I also run Mint Cinnamon.
I mostly use the volume (keyframable) effect, and when I click on another clip, the Kdenlive suddenly quits.

I have tried some other versions of Kdenlive, flatpak, the image ones, but nothing helps.

I have removed that effect from every clip in the timeline, and it's OK.
But that's not a solution.

I've noticed something strange.
When running Kdenlive from the "start" menu, i.e. via clicking on its icon, it runs 23.04.3 version, but when typing "kdenlive" in a terminal, it runs as 23.04.2 version.
It seems like I have two verions installed?? I don't know how.

So I've tried my project with the 23.04.2 version, and with the effects added to all of my clips, and I can jump between one and another w/o Kdenlive quitting. This seems to work only until I click on a clip in the project bin clip list ...

I can't believe this is hapenning

I also experienced crashes with the Flatpak version.

Running this command

Code: Select all

mkdir -p ~/.var/app/org.kde.kdenlive/cache/thumbnails/

fixed my issue. Not sure this applies here. Just FYI

It's been about 4 months since I had this issue and I've never actually found any descent solution other than reinstalling linux mint entirely.

The last thing I tried on my machine before reinstalling was to create a new user and run kdenlive logged into it. To my surprise, not only did kdenlive not crash, but some cinnamon elements were slightly different (I think I can remember the shutdown menu being different and possibly the settings app).

So, considering all this, I think these crashes aren't only cinnamon-specific, but also user-specific. Perhaps, cinnamon configuration got "corrupted" for my user and maybe the "corruption" was caused by some updates. For now the best solution I can come up with is to let go and reinstall mint, but I suppose one could also switch to a different user.

UNfortunately like many bug reports, that one was filed by someone with no clue how to properly file a bug report. Devs do not have the time or the inclination to hold their hands, esp. when they're unlikely yo have the same systems running.

Also, kdenlive is a known bug fest, has been for years.

trying to recreate the bug on a new user (didn't think of it at first) - but need to solve permissions issue to the disk where the project is located.


Re-installing Mint is not an option for now. Too much hassle just for one software.
For the time being I've moved onto Shotcut, well I am trying it out and it seems OK to work with, but it's learning a new software ...

Thnx
