Description Christophe PEREZ 2023-12-17 20:08:23 UTC

Crashes at every launch on my personal profile.
Doesn't crash on a fresh profile, but  I don't want to reset my profile at all.
Already tried to remove all kdenlive config files, unsuccessfully.
Compared kdenlive config between both profiles, unsuccessfully.
I've had this bug for over a year, maybe 2, or more. Every time I hope the new version will fix it, but that's never the case.

I know absolutely nothing about debugging, and I admit that it doesn't interest me that much.
Despite everything, I recompiled kdenlive with the instructions given, but for the rest, you have to tell me what you need.

Comment 5 diekuhrannte@web.de 2024-02-18 18:15:09 UTC

Hello Christophe PEREZ,
can you please report whether the problem still exists? Or can we close the bug report?

Comment 6 Christophe PEREZ 2024-02-18 19:48:03 UTC

Not solved at the moment with:
Linux 6.6.13-gentoo
KDE Plasma Version: 5.27.10
KDE Frameworks Version: 5.113.0
Qt Version: 5.15.12-r2
kdenlive: 23.08.4

Comment 7 David 2024-04-14 05:27:33 UTC

Just tried the 24.02.1-x86_amd64 appimage here. On Debian Bookworm under the XFCE desktop. Other KDE apps work fine under XFCE, for comparison.

Kdenlive just hangs. It displays the title/logo screen, the rest of the Kdenlive window is drawn behind it, then it hangs. The title/logo screen never goes away and the window behind it never responds to anything.

If I close the window, it will eventually terminate. Trying again gives me the message that Kdenlive crashed the last time it was run and offers me an option to reset the config files. I do that, but it still hangs.

I get this when started from the commandline:
Loaded icon theme: "breeze"
Loaded icon theme: "breeze-dark"
kf.notifications: Failed to play sound with canberra: No such driver
 = = = =
GOT Deleted file:  "/home/david/.config/kdenlive-appimagerc"
QPaintDevice: Cannot destroy paint device that is being painted

And the same hang.

I don't think this issue is fixed.

Comment 8 David 2024-04-14 05:29:02 UTC

Addition: When it hangs, using SIGTERM will not kill it. Only SIGKILL works.

Comment 9 TraceyC 2024-08-23 20:00:21 UTC

Another user had an identical backtrace in Bug 475173

Hey folks, just so you know, we are dropping Qt5 support soon.

Comment 11 Christophe PEREZ 2024-10-01 19:31:10 UTC

Solved with Plasma 6 migration and kdenlive 24.05.2
