Description L 2020-02-28 17:42:12 UTC

Application: kdenlive (19.12.2)

Qt Version: 5.14.1
Frameworks Version: 5.67.0
Operating System: Linux 5.4.22-1-lts x86_64
Windowing system: X11
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I tried to open a project that I previously archived using "Project > Archive Project" in kdenlive. It was opened using a different user (usera) on a different machine, but was extracted to the exact same path as it has been before archiving (/home/userb/Videos), e.g. I created a folder with the username of the other machine under /home and put it there. Kdenlive immediately crashes when opening the project file, before the GUI even shows up.
- Custom settings of the application:
None, as far as I can remember. The same bug occurs when using the arch linux packaged version or the appimage.

I am a developer myself and can try to provide more information as requested. For now, here is the output when kdenlive is run from the command line with --mlt-log debug:

```

Kdenlive project file in question

I'll provide the project file that crashes on opening.

Automatically generated crash information

Kubuntu user here (20.04.1 LTS) experiencing the same issue, though I'm attempting to open the archived project file as the same user that created the original. I've attached my copy of the crash information generated by KDE Crash Handler on my system.

Comment 3 farid 2021-03-03 21:08:32 UTC

I managed to open the attached project file with no crash, although I used placeholders for missing clips. Can you please test with latest appimage and see if you can reproduce?

Comment 4 stuart.lopresti 2021-03-06 19:04:10 UTC

In my case, using the latest version (both appimage and from the PPA) resolved the issue. Hopefully the same is true for the original bug reporter.

Comment 5 farid 2021-03-07 11:33:31 UTC

I will close it since we have 2 positive responses. In case OP still has issues please reopen.
