Description Nicholas Estrada 2019-04-23 01:50:55 UTC 
Kdenlive crashes immediately when I try to open a project that I was working on a week ago before the 19.04 update. I was leery of updating because I thought this might happen, but I decided to do it anyway and revert if needed. However, the worst is what happened. As soon as I try to open this project, it dies completely and I get the "Program Crashed" dialog.

Everything else seems to work just fine. New projects seem to save just fine. Opening these new projects also seems to work just fine. The new update just broke compatibility with old projects. Bug report output below:

Could you upload here your Kdenlive project file which makes the crash. It would be helpful to find the problem.

I get the same issue when I load a project created in version 18 of kdenlive. I uploaded my project file for you to test with. Please let me know if I can assist further.

@Nicholas, confirmed, your project crashes under Windows and Linux. Openend issue: https://invent.kde.org/kde/kdenlive/issues/174
Comment 6 emohr 2019-05-01 08:52:26 UTC 
@Jim I could load your project with place holder (Windows and Linux). I see the folders in the project bin. 

Try to make an archive project (project -> archive project) with the version the project works. Then open it under 19.04. I assume some clips have problems. 

And test with the AppImage 19.04 as well.

I downgraded kdenlive to 18.12.3 and made an archive of the project I previously attached.

I upgrade kdenlive on my neon system to 19.04.00 (MLT 6.14.0) and tried opening the archived project and kdenlive crashed.

I downloaded the latest AppImage, 19.04.00 (MLT 6.15.0), and tried opening the archived project and it loaded without any problems.

Please let me know if you need any further testing on my end.

Thank you for reporting.

@Nicholas, solved with commit: https://invent.kde.org/kde/kdenlive/commit/0b58e790d1d792b4ae55c5ed36ecb782eeae724b. 

@Jim, AppImage is what we recommend. If it’s working with the AppImage then your installation is not complete. 

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.
