Description Unknown 2016-07-25 19:48:23 UTC

Was working on a project, and while trying to click on a clip to edit its effect properties, Kdenlive crashed. I'm attaching the backtrace log from the crash.

Reproducible: Always




Bug discovered while using Kdenlive git master build via ppa:kdenlive/kdenlive-master.

Linux Mint 18 (ubuntu base) x64.

KDE Frameworks 5.18.0

Comment 2 Jean-Baptiste Mardelle 2016-07-25 20:34:33 UTC

did you use the qtblend effect on this clip (called Transform in effect stack) ? Could you attach the project file ?

Comment 3 Unknown 2016-07-25 22:54:39 UTC

I believe this was before the preview combo box was implemented, so yes, I think.

Attaching the project file, now.

Comment 6 Jean-Baptiste Mardelle 2016-07-25 23:13:10 UTC

Thanks for the project file. The crash happened because of a change I made yesterday to the qtblend filter (called Transform in Kdenlive).

The names of the parameters for this filter have been changed which caused the crash. I fixed the crash, but for projects created with the older version  of the filter, all parameters will be reset to default. If you want to recover your effect parameters, you can open the .kdenlive project file in a text editor and make the following replacements:

"transition.rect" should become "rect"
"transition.compositing" should become "compositing"
"transition.distort" should become "distort"

Thanks for the explanation, JB. It was a minor issue -- no biggie. :) Thanks for the fix!
