Crash when adding videos to queue from different channel groups after refresh

[asandikci]

• needs to be tested with NewPipe/Tubular to know if it is specific to this project

Steps to reproduce

• select a video from a channel group and start to play it
• after open another channel group and refresh it (fetch latest videos)
• select a new(?) video from this group and add it to queue
• make currently playing video fullscreen (?)
• exit from fullscreen and back to main menu (while video still playing)
• app crash

Is anyone can reproduce this? It sometimes occurs sometimes not. Probably I miss a step.

And is there any similar error on NewPipe/Tubular?

[whistlingwoods]

Yes, it was reported upstream on vanilla NewPipe version 0.24.1 by ktprograms (a developer himself btw). you can take a look on that.
TeamNewPipe/NewPipe#9609

Whether it can be reproduced on PipePipe remains to be seen because PipePipe fork started at codebase of 0.23.3 & never updated to "Refactor player and extract UI components" changes, specially "Create media session UI and fix player notification" in v0.24.0

I have a hunch that this bug belongs to changes post 0.24.0 or 0.24.1 version category. See issues in its release candidate , though most of them were solved but not all of them.

Edited: This issue was definitely not reported there, but it was found 2 releases after that by a tester & power user, a dev himself. If this can be reproduced on any working 0.23.3 versions still around there then maybe but I am saying is wrong.

Does this comment helps debugging this?TeamNewPipe/NewPipe#9609 (comment)

@whistlingwoods Thanks for the suggestions and sources. I'll investigate in my free time.
