nlesource: assertion when seeked while removed from the composition during stack activation
When I drag a clip onto the timeline; then drag it off the timeline on the left side; then once again place it on the timeline and drop it Pitivi will crash.
It has been found that removing the line object->in_composition = FALSE; from the nle_composition_remove_object function in nlecomposition.c is a temporary fix to stop Pitivi from crashing.
To reproduce:
- Select a clip and drag it over the timeline.
- Drag the clip off of the timeline to the left border.
- Drag the clip in the other direction and then place it on the timeline.
If clarification is needed on how to reproduce the bug, I can screen record the steps.
Attached is the log from GST_DEBUG.log.tar.xz
