Dear Maintainer,
I just tried to collect some more info from this crash.
I got this by using "peek --backend=gnome-shell"
inside a gnome/wayland session.
Using some reverse debugging, I guess all happens below function
peek_post_processing_ffmpeg_post_processor_generate_animation_async_co,
that seems to translate to function generate_animation_async
in ffmpeg-post-processor.vala.
As I have near to no knowledge of vala I just guess,
that the args array gets automatically destructed at function end.
But before the content gets appended to argv.
There function append_vals may not do a deep copy,
which leads then at argv destruction to the double free.
This should be checked by someone with more vala
knowledge than me.
At least a package built with attached patch does
not crash and could produce a animated gif.
Also attached some more details on the debugging.
Kind regards,
Bernhard
