Description Adam Spiers 2018-11-03 13:20:29 UTC

STEPS TO REPRODUCE

1. Create a custom effect
2. Apply it to a clip
3. Delete the custom effect
4. Save the project
5. Restart kdenlive
6. Reload the project

OBSERVED RESULT

Dialog box appears saying something like "Effect crop:test not found in MLT, it was removed from this project".  After clicking the OK button (which is the only option), the effect is no longer applied to the clip. 

EXPECTED RESULT

Any effects remain applied indefinitely after a custom effect is removed.

SOFTWARE VERSIONS

Seen in both 18.08.2 AppImage, and 18.04.03 installed from Packman rpms on openSUSE 15.0

ADDITIONAL INFORMATION

This effectively makes renaming a custom effect a destructive operation, because the only way to do it is to save a new custom effect with the new name and then delete the old custom effect.  This is particularly inconvenient if the custom effect is applied to many clips, because then you have to manually reapply the renamed custom effect to each clip.

Following your step 6 creates a crash with the AppImage 18.08.3. I can’t open this project anymore. With Kdenlive Windows version 18.08.2 it works.
Try with the AppImage 18.08.3.

Can you please test the latest AppImage and see if you can reproduce?
