Hi,
suddenly when I try to open kdenlive, I get this error:
kdenlive
ZZZZZZZZZZZZZZZZZZZZZZZ
STARTING TASKMANAGER CLOSURE, ACTIVE THREADS: 0
EXCEPTIONS: QList()
ZZZZZZZZZZZZZZZZZZZZZZZ
= = = =
GOT Deleted file: “/home/xxxxx/.config/kdenliverc”
==== FOUND CUSTOM SHORTCUTS!!!
QPaintDevice: Cannot destroy paint device that is being painted
I tryied remove and reinstall and nothing changes. Any suggestion?
P.D.: I’m using KDE Neon. Kdenlive installed from: apt get install kdenlive
It’s a problem with the frei0r plugin. If I remove this plugin, kdenlive start, but it say that this plugin is missing…
Download and recompiled again. Now seems is working again.
Hi,
How do you resolved your problem?
Because I’m also under kde neon, and I also have this problem.
This is probably your problem:
Try using the appimage from here instead: Downloads - Kdenlive
Hi,
first move the plugin:
mv /usr/lib/frei0r-1 /usr/lib/frei0r-1_backup
check if kdenlive run, if it run download and compile frei0r yourself.
git clone GitHub - dyne/frei0r: A large collection of free and portable video plugins
cd frei0r
mkdir build && cd build
cmake ..
make
sudo make install
Yes, I know… but I’m a stubborn. 
Then you really should be reporting these problems to that package maintainer. We don’t maintain it and can’t fix problems with it, and the people providing it don’t appear to be active here to see what you post about it …
Your problem isn’t “Kdenlive crashes” - users of the packages we support don’t need to be building frei0r themselves for it to work. And we can’t really help you with “I’m (determined to keep?) using broken packages made by someone else” if you’re happy to ignore red flags like that.
You’re right, I’ll keep that in mind next time.
Thank you @Ron & @David_Rotger
I’ve installed kdenlive Flatpak from
kdenlive.org and It works perfectly now.
Have a nice day everyone.
good catch. finally saw this thread from https://bugs.kde.org/show_bug.cgi?id=507218
frei0r-plugins needed rebuilding against neon’s libopencv, so i took the opportunity to backport a much more modern 2.3.3 version from plucky, rebuilt mlt as well.
tested to work on all editions. will be available after the next snapshots are released
Hi Carlos,
opencv uses protobuf - which chokes on mismatched versions - and kdenlive links to opencv as do some of its deps, which opens the possibility for them to be mismatched if they are updated independently.
I’m not sure how you guys manage library transitions in neon, but opencv needs to be flagged as one that needs all of its deps rebuilt when you update it. This tends to become a faq for several distros once or twice a year when opencv updates roll out, and it’s surely not only kdenlive which is affected by it.
